I need to design a simple single stage common source amplifier using an N-type enhancement mosfet (2N7000). The gain Av should be 100. With sufficiently large drain resistance -- which implies either a high supply voltage (s. image below) or respectively low drain current you can achieve such Av : [ATTACH=C

i need a help regarding how to design a power amplifier using ADS tools. is there any design guides available? pls help there're many examples for this in ADS.
usually in power amplifier design u need to use LSSP , which is based on HB simulation , small signal S parameters are not ususally used in PA also it will be not vaild at all if u design a class C PA so use HB , or LSSP khouly

Hi there! I need to design an amplifier using ATF-36163 transistor. I also have to use Ansoft Design (I have not really get the hand of using this yet). The amplifier is to operate at 5Ghz (that's the only requirement in terms of variables). I already have the S parameters in hand. However, I am quite lost on how to (...)

Hi! I need to know why I'm not getting logic 1 (5V) as the output in the following circuit. This is a circuit used to obtain AND operation using mosfet. 105027
The simulator does provide a right leg terminal so why don't you use it? In any case an instrumentation amplifier needs some means to enforce a common mode voltage in the specified range. If you don't use a RL circuit, you must have Mohm bias resistors to ground at the inputs.
Hi, I would like to design an HF power amplifier but all the schematics i have found are not in the desired bandwith !! SPecifications of the amplifier: Input signal : 0 to 12V between 800Khz and 5Mhz OUtput signal: 0 to 12V but 60W !!!

Hi people, I'm trying to design a 1 Watt push pull amplifier using dual NPN RF mosfet at 40MHz and a 24 Volt single supply. I'm not using any inductors or transformers. I'm not sure how to bias the mosfet correctly. What type of biasing circuit should I be using ? Since I'm (...)
Dude, your schematic looks like shit. Its very difficult to understand it. The PMOS transistors will show Id as negative that is a convention and does not mean that something is wrong. How have you designed this amplifier? How are you generating the bias voltage for the gate of M1 and M2?
I'm using IRF610 mosfet to build a common source amplifier. The mosfet is n-channel enhancement mode. I have read everything I could find on mosfets, read my lectures and still I don't understand how to do this. This is the best schematic I could find but I have no idea how to choose m
Hi, You will need to know and work out the biasing for the transistor eg. the collector resistor value and what is the power supply voltage you will be using, also you will need to bias the base as well. Not to mention working out the value of the decoupling capacitor at the emitter, based on the lowest cutoff frequency you would like for your amp

Hi All, Where can i find "class B amplifier using opamp" schematics? Thanks
Hi; Any references on designing amplifiers using BJTs. I need a gain of approx 20dB.
If Vsource = 3 + 0.1sin(1000t)V and Vout = -2sin(1000t) Gain would be Av = -20, correct? It would not be correct to divide -2/(3 + 0.1), but -2/0.1. How would one remove offset from the input signal when designing a mosfet transistor amplifier using only 1 transistor? -Thank you Added after 1 hours 1 minutes:[/col
