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. In a differential amplifier biased with a given tail current I, to increase the overdrive voltage by 2X without changing input capacitive loading, we should (a) Increase W by 2X and reduce L by 2X (b) Reduce W by 2X and increase L by 2X (c) Reduce W by 4X and keep the same length (d) Increase W by 4X and reduce L by 2X

can you do question iii please?
