Abstract

An operational trans-conductance amplifier circuit having a voltage clamp circuit. The clamp circuit utilizes low area and power overhead, has a sharp clamp characteristic, and little degradation in the small-signal DC gain at the “knee” of the clamp characteristic. The clamp circuit includes a comparator circuit and a current control circuit. The amplifier and clamp circuits may further include a clamp voltage generator circuit.
