Bias-temperature induced damage mitigation circuit

摘要

A circuit that regulates electrical current flow through an integrated circuit involves a sequencing circuit connected to a clock signal generator, the sequencing circuit configured to, responsive to receiving a clock signal from the clock signal generator, generate a set of sequencing signals that includes a first switching signal, a second switching signal, and a disable signal. The circuit also involves a switching circuit connected to the sequencing circuit, the switching circuit configured to receive the first switching signal and the second switching signal and a current mirror connected to the switching circuit and the sequencing circuit, the current mirror configured to receive an activation signal from a current control logic circuit and to receive the disable signal.
