Dear all, I am a student. If anyone can help me to answer this question, I would greatly appreciate it. I am designing an output matching network. Is there a way to determine the output impedance of the transistor from its load pull characteristics? As far as I know, we can extract optimum load impedance from load pull simulation. But how to
I'm trouble-shooting a pre-amp from a 70's Fender Rhodes electric piano. Pretty simple device... but I realized that I should poke around to see what equivalent transistors I might need. With rare exception, the designer selected 2N3392s for his go-to transistor. Amplification, buffering, tone controls... all 2N3392s. The top rail is 25 (...)
by calling it N channel do you mean its basically a IGBT equivalent of a NPN bipolar transistor, except that instead of a gate that conducts it has a isolated mosfet like gate(whatever the IGBT inner structure was) ?
You are correct. But is there any other transistor that I can use instead of this one? I can not find it in my regular suppliers.
I'm going to design a PA for 4 to 10 GHz band. But the required transistor given for design is Mitsubishi MGF2116 which is not available. What is its equivalent? Anybody has any idea?
Hi, I need to replace a broken transistor, is a BFR36, but I'm unable to find the same transistor at the local electric shop; I can't exactly figure out which equivalent would be ok: by a search on Google I've seen a pair of possible candidates: 2N5109 and 2SC1068; which of these two would be fine? Or maybe someone could suggest me a good (...)
I admit I need to see the photos to at least give a try to identify. Having said that, if the transistor with 014 is in TO92 package, it is probably 2N9014 - a general purpose NPN transistor. A rough equivalent is BC547 or BC549.
I am looking for an smd version or equivalent of the 2n5109. It will be used in an HF preamplifier with high dynamic range, because this is a power transistor.
Dear Friends, I have searched lot in the google, I couldn't get it. I request you to show me document for the small signal noise equivalent model for CMOS transistor and HEMT transistor. If you know somebody, complete analysis document for the noise small signal equivalent model of CMOS (...)
Hi folks, I need to replace a burnt 2SC3420 transistor from a 1/10 Eztec RC Toy car that runs on a 9.6V/1000mah nicd/nimh battery pack, brushed 380 motor for some kind of reason the prices of those specific transistors are insane ( for what it is) so looking for a replacement part I came across a forum where someone was saying that you could saf
Hello! I need the equivalent of ZTX458 and ZTX558 transistors.Any help will be appreciated. Thanks & Regards Deepak
It can be found easily from its small signal equivalent circuit.( hint: cross coupled transistor oscillators )
I want to model the following attachment by matlab simulink. but I don't know that what is "TSC4429" IC! it is "gate driver" of "Q transistor". can you give me datasheet or equivalent circuit of "TSC4429" IC? how model it in matlab simulink? 116531
you didnt state the voltage nor frequency......... but you could use a transformer or op-amp ........depending on the requirement and signals
I would like to see how all the parameters of a transistor model are connected as a circuit. when we are trying to use a transistor in a circuit spice converts it into its linear form by replacing it with its linear representation. I would like to know what transistors linear representation looks like. 1. For this I've chosen BSIM 4v4.5 (...)
... 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.
Hye all..I'm doing a project for my degree now. The project is about designing the oscillator wave with centered frequency at 13 GHz. I decided to use GaAs MESFET NE71383B as my transistor. 112034 The problem is, when I look into the schematic diagram of that transistor, there are another transistor place in it, la
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.
I need the equivalent of a ac188 transistor.The transistors aren't available anymore.They are germanium transistors in pnp configuration. Thanks.
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 (...)

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.

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
