If you look at the equivalent schematic shown in the datasheet directly below the functional block diagram, you surely understand how a high reference input current can be generated - by forward biasing the Ref-Cathode (base-collector) diode. This won't happen in a typical application, e.g. the datasheet reference circuits, but can happen under ci
hello what is this personality and equivalent 362 ? hb100 rosh thanks 125728
Presently, the diode is shorting the DC/DC output to input. You need two diodes towards 89S52, one for 3.7 and one for 5V, or equivalent electronic switches with lower voltage drop.
Hi! First I want so say that I'm already familiar with the equivalent electrical circuit of a photodiode you can find in the bibliography. But the thing is I'm having troubles in something I thought it should be straight forward. I want to build a new OpAmp-based transimpedance amplifier for a photodiode, but before I plug in the PD, (...)
ferrite beads tend to be low Q and used more to reduce radiated noise transients or RF noise. Better way is to use 100 Ohm CAT5 type transmission lines from 50~100 Ohm CMOS LOGIC ( e.g. ALVC types) and termination R @ V/2 or equivalent Thevenin circuit with Pullup/dn if you want best speed and noise immunity. THen use large CM choke around cable
I found that VS-31DQ09 is obsolete so that can i use SB5100 as equivalent
Hello, I hope this question makes sense? The Resistors in the above diagram have a minimum Wattage rating based on the requirements of the circuit - do diodes have a similar or equivalent rating? e.g. If I k
you should use the diode spice file, ADS has some equivalent circuit, but need you input some parameters.
Hello everyone!!! I tried hard to search CT100 's Datasheet if anyone have datasheet link or of it OR equivalent to it please let me know thanks a lot
diode model used in circuit seems to be creating trouble, diode Model DX does not have any resistance (Model Parameter RS) defined, which is equivalent of making it R=0 for this device. Such models are hard to converg. I tweaked this model to have realistic value RS=100U and relaxed couple of other simulator options and it works for me. (...)
hi guys, can anybody provide me 1n6642 pspice model or is there any equivalent for 1n6642 with same physical characteristics, pls reply soon
Since you have terminated the output with equivalent voltage source, the circuits becomes exactly symmetrical -->so the circuit can be folded into one tail source cascoded with Input pair (2w/l) & the nmos load as diode connected with (2w/L) -->Now caluculating gain from Vcm to output -->we will get gdst/gmn (<<<<1) [gdst-->gds of the tail transist
I have a very little doubt on the basics of a diode. After a small interval I found the answer but I don't know that I am correct or not. Here is where I stuck for 20 min As diode starts conduction when the voltage across it is 0.7 volt (general condition). After studying piecewise linear model, the equivalent circuit of a (...)
I need datasheet or equivalent for SCR EDG06-08 ( manufacturer looks like Siemens logo) And also diode Mitsubishi IFM29D Any help is greatly appreciated.
I have measured the S-parameters (S11) for a Schottky varactor upto 40GHz. I have a desired equivalent circuit model for my device. I would like to extract the equivalent circuit parameters to fit the measured S-parameters. Is there any software (preferably open source) that can help me do this extraction of parameters?
I guess, it might be a MOC3161 (optotriac with zero crossing control) equivalent. But if it's a phototransistor though, most have an industry standard pinout, you can refer to similar types. The LED can be easily identified with a multimeter (in diode voltage range), also the base pin of the optocoupler if connected to a pin.
Hi, I have a photodiode equivalent like this: 93251 Can I transform this equivalent in a series between a voltage source (Vg) and a resistance (Rg). Because this photodiode is the input of the negative pin of an opamp that work like an integrator to amplify photodiode's signal and I need to calculate the (...)

I need to find the equivalent replacement of mv2109 varactor diode.which parameter i should consider while selecting the replacement? I am looking for component in digikey & mouser. So please help me to find the available replacement from the supplier. I need this varactor diode for my FM stereo transmitters circuit (BH1417)... (...)
A zener diode would be an obvious answer. If it has a high enough watt rating then you don't need to install a resistor inline. Or try the equivalent of a 1A zener, made from 5 diodes in series, each with a 1A rating. If the total drop is too far short of 3.3 V, then add a sixth diode. If necessary you can 'bend' (...)
Hi, Can you point to me an equivalent to the transistor BU508DFI? Thanks, Bruno

Hello there, I'm implementing an AC/DC/AC converter with an equivalent model of a DC capacitor. But right now I'm having an error message which read "Switcht that bounce D1 (in circuit)" D1 is the first diode in my AC/DC converter can someone help me. I do have that when I insert an inductance on the grid side Many thanks
When you see 'Vcc' is usually means bipolar, the equivalent in CMOS would be labeled 'Vdd'. It happens, that 74HC etc. series uses VCC rather than VDD, although the devices are not bipolar. You'll notice the same with a lot of CMOS devices. In other words, relying on just the name "VCC" has a good chance to jump into conclusions.
Explain the equivalent Circuit diagram of diode connected Nmos and with formulas.
I have designed a SPDT switch on ADS. The problem is when taking practical results the bandwidth comes out to be only 100 MHz. But in simulation it is 500 MHz. I am using a shunt Switch configuration and using equivalent models for PIN DIDOES.Design file is attached. Kindly comment for increasing bandwidth
Does anyone know how to design a simple PV module using PSPICE? I tried a current source in parallel with diode and resistor along with series resistor(cells). As I have just started using PSPICE and it is my second year in college and I am just trying to enhance my skills in this software and renewable. If anyone who has the complete deisgn modu
The IC is an integration of an array of darligton transistors at each channel. Pin 1 of the IC is equivalent to the base of an NPN transistor and PIN 16 is the collector of the same transistor whose emitter is grounded. A free wheeling diode is internally connected from every output pin to a common pin 10 in your case. Below given is the internal
you can use hardwire connection for the diodes which are ON and no connection for the diodes which are OFF Added after 4 minutes: i.e. for each reconfigurable state you should replace diodes with ideal connection. If you want to be more precise, you can use the equivalent circuit model for the ON and OFF
When omni directional behavior is not required, first start with dipole/patch over a ground plane to get some gain. When using a real microwave diode (BAT15, or equivalent), you can get significant increase of sensitivity by matching the diode to your source. In a parallel equivalent circuit, the parallel resistor will be (...)

A photodiode has two equivalent resistances: series and shunt .. The series resistance is several ohms and the shunt resistance is 10MΩ - 100 000MΩ .. The series resistance can be obtained from a particular diode's data sheet .. Regards, IanP
hi there, the most primitive way of testing a transistor is to test each junctions' resistance... note that a working diode has a forward resistance and it has a reverse resistance equivalent to infinity... here's what to do, measure the forward and reverse resistance of each of the junction... a non-working transistor will have at least
consider a current source of current I=gm*Vgs and the drop on this source is Vgs then the equivalent resistance seen is R=V/I=Vgs/(gm*Vgs)=1/gm
Hello. If the solenoid is powered by DC current this current invokes a magnetic force. But if the solenoid is powered by pulsed supply (PWM), which current is equivalent to the DC current (The pulsed current should invoke the same magnetic force)? Measured between solenoid and reverse diode or supply current? It is average or rms value? thank
Hello. I need to measure selenoid current. (The selenoid controls presure reducing valve) It is powered by PWM. I don't know where to measure the current. In series with switching transistor or in series with selenoid and reverse diode? The measured current should be equivalent to DC current. Thanks for help. michal
we all know that differential ckt puts out 2x the output voltage swing but how come it's small signal voltage gain is the same as the equivalent regular non-differential pair. Let's say a CS with diode connect would have Av=gm1/gm2, the differential gain uses half ckt so it would have the same gain? Sorry, i don't understand that... it doesn't fo
Dear all Electronics Engineers, Kindly I have a question which is very important for me, so pleas, pleas advice and help me... I have to repair a transceivers work in 5.8GHz and 5.4 GHz rang, I found the faulty component, it?s a surface mount diode (it has a cathode label as I draw it in the picture but it?s not that clear, and I take a
For the first question : We take the output fron the transistor that is not diode connected ,because the diode connected transistor is equivalent at the small signal analysis to a resistance of value 1/gm which is usually a small value .The gain at the output of the unloaded amplifer is equal to Gm*Ro where Gm is the amplifier's (...)
If you short the drain and the gate in a MOSFET, in the small signal analysis it becomes a diode-connected transistor i.e it is equivalent of a resistor of value 1/gm .Note that the diode connected MOSFET is always in saturation given that its Vgs is larger than Vth in other words it never operates in triode .If you short both the drain and (...)
munich1806, Test current is the current at which the zener breakdown voltage and equivalent internal impedance specifications are guaranteed. Currents higher than the test current result in slightly higher breakdown voltage and lower internal impedance. Conversly, currents lower thatn the test current result in slightly lower breakdown voltage a
