Hello all,
I have already set the bias point and all of them are in saturation. This amplifier has gain of around 35 dB.
My concern is: when the values of input ac signals are changed, the dc value at the output node is changing. I am afraid if it is possible for any of the transistors to exit saturation. If it is possible, should I bias the output node too? How can I do that?
Please note that I want to avoid resistors for biasing purpose.
(above two are PMOS. please ignore the position error of the sources in PMOS. sources are connected to Vdd)
Any suggestion, tutorial, link will be greatly appreciated.
Thanks
