Hi
I decided to make a variable lab power supply from a computer ATX power supply.
There are +/-5 volt and +/-12 volt DC voltages ready for use (from ATX power supply).
Any suggestion how to design a adjustable +/-1.5 volt to +/-25 volt symmetrical output?
(I.e. negative and positive outputs...
Very good. Is there any website to find the desired electronic elements having something like advanced search or the choose is made by experience?
By the way I used Orcad 16.0.1 and the result was nothing even when I changed the gm parameter of J110 PSpice model. but the EWB version worked fine...
Re: FET based Wien-Bridge Oscillator
Yes, Just a single FET, no matter the amplitude of oscillation or it's frequency just a single FET.
It's something like a competition between friends!:|
Re: FET based Wien-Bridge Oscillator
Would you please suggest some changes while the main idea is unchanged? I mean a phase shift oscillator with just a single FET even with imaginary parameters(high gain, low output impedance).
Re: FET based Wien-Bridge Oscillator
I mean what the value of elements should be to see the oscillation in time domain analysis of PSpice?(maybe a sine wave)
Re: FET based Wien-Bridge Oscillator
1) You are right. It's a phase shift oscillator.
2) I have no problem with the op-amp one, the problem here is how to see the oscillation results in Pspice by using FET?
Re: FET based Wien-Bridge Oscillator
Can anyone help with parameters and how to get the desired results?
f=1/(2*pi*R*C*√6)
|A|=gm*RL
RL=(RD*rd)/(RD+rd)
Re: PAPER REQUEST
Abstract�We consider a multiuser multiple-input multipleoutput
(MIMO) Gaussian broadcast channel (BC), where the
transmitter and receivers have multiple antennas. Since the
MIMO BC is in general a nondegraded BC, its capacity region
remains an unsolved problem. In this paper...
