An operational amplifier contains an open-loop transfer function specified as:
A(?) = 104/([1 + j(?/31.4x106)][1 + j(?/314x 106)])
The op-amp is used within a negative feedback configuration containing a dc closed-loop gain of 100. Draw Bode plots of the phase and magnitude of the loop gain of the amplifier. Estimate the phase and gain margins of the closed-loop amplifier configuration.
