Hi all,
Please refer the following diagram of two stage opamp..Vdd = 1.8V, Vbias = 1.234V, Cload = 35pF
When I give 900mV as input to both input terminals the output is 900mV and all the transistors are in saturation.
My problem is:
1When I connect it in non inv. config. with resistive feedback(Rf = 1K, R1 = 1K) I get 100mV out if input is 1V..Not working as amplifier..
2. How to find the offset voltage of opamp in cadence
Thanks in advance
