Abstract:
A method is described for performing an automatic internal trimming operation that can compensate process variation and supply voltage variation in an integrated circuit. A reference signal is applied when the integrated circuit is in an automatic internal trimming mode, and integrated circuit timing is trimmed into a predetermined target range after applying predefined reference cycles.
