you didnt state the voltage nor frequency......... but you could use a transformer or op-amp ........depending on the requirement and signals
how spice replaces the transistor with its equivalent model in the sparse matrix while performing MNA It should be quite obvious from descriptions of circuit simulator operation what SPICE or any SPICE based simulator does. It performs an initial transient solution to determine the operation point, then calculate the node impedan
... the channel thermal noise does not move to the gate of the transistor? In reality it doesn't move to the gate, of course. But if you need or wish to model its equivalent gate noise voltage, you can use the thermal_noise_current/gm formula to get the equivalent thermal gate noise voltage, of course.
There's no direct replacement. But both types are still available from catalog distributors, e.g. Farnell. A functional replaclement would go either for lower or higher power transistors and possibly SMD types.
Have you ever checked model parameters page 6 ?? They have marked as " Series IV Libra TOM Model" on the bottom.. You will place this equivalent transistor and fill the parameters in according with in the datasheet.
The 2SC1162 is classed as a LF power NPN transistor with a "transition frequency" of 180MHz rated for 2.5A. These would be the critical specs with some tolerance for lower currents and >150MHz for 100MHz operation. Everything else is optional but will have some effect. You can wind your own coils with a coarse thread bolt and stiff wire and
I have started some rough literature researches - and the result is: Yes - we can find two different approaches for building a small-signal equivalent diagram for the common base (CB) case. It is common to represent the BJT alone using a current source (gm*Vbe) between collector and emitter. This applies also to transistor amplifiers in C
I named each transistor as well as the "control" node "X". 109037 F will be low if X is high or TR9 and TR10 are both ON, that means A and B are high F will be high if TR7 is conducting (X is low) and at least one between TR5 and TR6 is ON (that means at least one between A and B low) That is: X A B F 0 0 0 1
I am looking for a transistor similar to LP395. Since LP395 is available in TO-92 package i couldn't use it for my application. I need a transistor with same features as LP395 but with surface mount options. Please reply as early as possible if any one knows a similar SMT transistor.
Those are germanium transistors later in India, BEL (now it seems stopped consumer electronic items) came up with Bel187 and Bel188 complimentary silicon pair in modified TO92 with in built heat sink tab. - - - Updated - - - rock94, I do have it, international postage will eat and it would not be wort
How to represent mosfet in triode and sub threshold region. like self cascode transistor one transistor is in saturation and another once will be in the triode region . i want to calculate output resistance and effective trans-conductance of self cascode MOSFET. can any give the brief note about this topic. thank you
I know that one can introduce programmability in FGMOS transistor using Fowler-Nordheim Tunneling and hot electron injection, but am unable to implement this idea in cadence design tool virtuoso. I would like to know how to generate this equivalent model of programmable FGMOS in virtuoso using tunneling and injection? What are the circuit component
Hello, I tried to build this circuit in the link below with some 2SC1971 RF transistors I received from Ebay. Needless to say I learned that they were counterfeit and that getting the actual genuine 2SC1971 transistor is actually hard to come by so I looked up an equivalent transistor. As I read on some sites the NTE342 is a (...)

Hi, I need to use an SMD equivalent of the npn transistor BC149C, is there any device that meets the specs?? thanks a
Hello, I would like to build this PSU because I like discrete. I am looking for a transistor equivalent for the 40411 If you can suggest similar circuits with newer transistors please let me know as well.
I think you're considering vgs = vin. As I understood from what you wrote vgs = V1, so now its not important what vin is , the transistor considers vgs and therefore produces a drain source current of ids=gm*vgs. Therefore the vth will be vin (the main input ) and the rth will be 1/gm. I think you have considered the source voltage to be V1 and
Can be reduced to a simple capacitance ratio problem, I think. transistor capacitances that are probably larger than assumed load capacitance have to be considered, too. Beside being unrealistic, infinite series inductance would involve infinite supply settling time.
You need to show the circuit. Same applies for your transistor question.
which transistor function is same as MRF947T1 transistor? Is there any link? MRF947 is not available in market.
Anyone know the equivalent transistor for C2570....................?
Anyone can give me the name of MRF947T1 equivalent transistor....................? MRF947T1 is not available in our nearby give me the name which replace this.
i need an equivalent for this transistor: 2n3643 thanks
anyone suggest an equivalent transistor to this among the 2Ns, TIPs, BCs, BDs and BFs etc There are plenty of these available in multisim but bugger all 2SCs.
Hey all, I'm currently looking at various current mirror topologies. Take a look at attached picture. The first ("normal" current mirror) and third (low voltage cascode mirror) are described in Razavi's book. The second I have stumbled upon looking at other designs. Curious about there performance, I simulated all three topologies: M1/M3 rather
Can anyone please help me find some replacements for transistor A1141 of my amplifier?
Hello neazoi, to find a discrete equivalent of this transistor will be very difficult. They must not only equal in data, but also they must have a thermal connection. Herre you can only compare datasheets of single JFETs and try to connect it together in thermal way. If you need it as a replacement you can ask
The equivalent circuit looks correct. As a first step you'll need to determine the DC operation point to determine the actual transistor parameters. AN exact analysis requires to solve a nonlinear equation system, so you'll most likely use some simplifications for the calculation, e.g. constant Vbe and current gain. Secondly, the small signal

I can't seem to find the values for a potentiometer I am hoping to use. Well I found what I think is the value @ but I'm not sure if it is correct for this particular one as the last marking isn't available. The pot reads J then a circle with a lightening bolt or similar then 10

Hi. I wanna know about each case MOSFET equivalent circuit when mosfet is in ON and OFF. what is different each case? Thank you.
hi, virtuoso tells you these values. just simulate and print or annotate the component parameters of the transistor you want. a lot of parameters will be listed and you can search for the related capacitances. I guess, the input capacitance of an inverter is Cnmos + Cpmos. Cnmos = Cox,n + Cgd,n + Cdb,n + Cgs,n. Cpmos is the same as nmos. Virtuoso

Between the 12V battery and the motor, you can use a series transistor (sometimes known as pass transistor) such as IGBT, preferably that can handle rating 2A or higher. Vary the IGBT gate voltage by passing PWM signal (from a microcontroller) into a low-pass filter (to get equivalent DC voltage at IGBT gate) to vary the IGBT emitter (...)
