Hello everyone,
I use cadence to simulate an amplifiers offset voltage, but it shows the offset is 170mV. I think it's too big. My method is as following: First, I connect the negative input and the output of the amplifier. Then, I add a DC signal at the positive input and sweep DC voltage. I get output voltages changing with the DC signal. When output is zero, the positive input is about 170mV. So this voltage is offset voltage. I don't know whether this method is corret. Can anyone tell me?
Thank you in advance!
