Abstract
A soft clipper circuit in CMOS technology not only allows the knee to be programmed, but also the slope of the curve after the knee to be programmed. This is accomplished by putting a second transconductance in parallel with the first transconductance, and using a switching circuit to connect the output of the second transconductance to that of the first transconductance when the knee level is reached. This is determined by a comparator which has an input coupled to the second transconductance and controls a control node of the switching circuit.
