Abstract

A block power switch may be embedded with electrostatic discharge (ESD) protection circuitry. A transistor portion of the block power switch may be allocated to act as part of ESD protection circuitry and may be combined with an RC clamp to provide ESD protection. Adaptive body biasing (ABB) may be applied to the block power switch to reduce on-chip area and decrease leakage current of the block power switch.
