ABSTRACT:
An A-to-D converter 300 has a comparator 126 with a number of comparator cells 902. Each comparator cell 902 includes a current mirror 1700 that reduces kickback noise. Current mirror 1700 includes a bipolar current mirror 1705 and an NMOS current mirror 1709. The bipolar current mirror 1705 provides an ac ground paralleling NMOS transistor 1704 in the NMOS current mirror 1709 to reduce kickback noise.
