A certain Class-E CMOS amp is in full saturation for

it is off. The supply voltage is 12v. What is the
steady-state impedance of the source at the fundamental
frequency?


Now, now, Cecil! Don't sully the thread with facts !-)

This needs a 12V transistor that switches in about 25pS. Would that be
likely on a current chip?
