Virtual ground of an OP-AMP (a) Is formed only with negative feedback (b) Is always an AC ground, may occasionally be a DC ground (for PMOS) (c) Is coined as a terminology where the input signal splits equally between the terminals (d) Leads to the concept of almost zero difference between the two inputs (both DC and AC) using feedback 2. In an OP-AMP based circuit (a) Phase margin of the closed loop transfer function is a measure of stable operation (b) 45° is a desirable phase margin as it balances the frequency domain stability and the time domain settling optimally (c) Absolute open loop gain numbers are not that important, as long as they are large (d) 45° is only achieved when the RHP zero is placed on one of the poles 3.
