Circuit and method for constant slew rate in high voltage charge pumps
Abstract:
An integrated circuit includes a non-volatile memory, a charge pump that generates high voltages for programming operations of the non-volatile memory array, and a charge pump regulator that controls a slew rate of the charge pump. The charge pump regulator generates a sense current indicative of the slew rate and adjusts a frequency of a clock signal provided to the charge pump based on the sense current.
