Abstract
The circuit of the present disclosure is a high-speed precision clamp (voltage limiter) for overvoltage or undervoltage protection. One aspect of the circuit includes using a peak detector in the feedback path of a clamp having a super-diode architecture. The resulting circuit performs well for high-speed applications. The peak detector can be replicated (at least in part) to accommodate a multiplicity of phase-shifted input voltages by using only one common peak detection capacitor and ensuring area savings in integrated-circuit implementations.
