How can i increase the swing of the unity gain amplifier, i tried to increase and decrease the (W/L) of the transistor but the swing is not very good.

thanks in advance
 

Re: Unity gain amplifier

have u checked its delay times
i.e.

its risetime and falltime

time period
check these things also

Re: Unity gain amplifier

try increasing the biasing current... it would help.....

Re: Unity gain amplifier

Could be your opamp is limited by the input common mode range. Try to increase the slew rate of your opamp, that is by increasing the biasing current, which will help in fasten the rise and fall times.

Unity gain amplifier

Increase the tail current of the differential pair can increase the slew rate. But you have to check the phase margin.
