Abstract
A high-voltage level shifter circuit that is capable of level shifting a signal from a low-voltage rail to a high-voltage rail for effective gate driving of a top power switch, with a short propagation delay and a high common-mode transient immunity (CMTI). The high CMTI high-voltage level shifter circuit can include a differential input and isolation stage, a high dv/dt sensor and cancellation stage, at least one differential and common-mode gain stage, and an output buffer stage.
