A source follower is required to deliver a 0.5-V peak sinusoid to 2-kΩ load. If the peak amplitude of vgs is to be limited to 50mV, what is the lowest value of ID at which the MOSFET can be biased? At this bias current, what are the maximum and minimum currents that the MOSFET will be conducting (at the positive and negative peaks of the output sine wave)? What must the peak amplitude of vsig be?
