Abstract
A power regulation scheme for high voltage output in integrated circuits is realized in a regulated high voltage generator, a voltage clamp, and a power regulator connected between the voltage clamp and the voltage generator. The voltage clamp produces a clamp current during a voltage limiting operation. A regulating clamp current corresponds to an initial limit voltage of the clamp. The power regulator senses the clamp current and suspends voltage generation as the limit magnitude of clamp current is attained. The clamp current is mirrored in a current comparator circuit that triggers a stop signal to the regulated high voltage generator, thus saving power.
