High-dynamic range low ripple voltage multiplier

摘要

A voltage multiplier (10) including a first clocked multiplier stage (12) having an input and an output and a second clocked multiplier stage (14, 16) having an input and an output is provided. The voltage multiplier further includes an input level regulator (18) coupled to the input of the first multiplier stage. The voltage multiplier further includes a feedback bias control circuit (32) coupled to the input level regulator, wherein the feedback bias control circuit is further coupled to receive the output (50) of the second multiplier stage, and wherein the feedback bias control circuit generates a feedback signal (58) affecting an output of the input level regulator based on a comparison between a voltage proportional to a voltage at the output of the second clocked multiplier stage and a reference voltage.
