Abstract

a differential T/H amplifier with a built in digital AGC function is realized in GF 65nm bulk CMOS LPE technology. The design consists of a linearized OTA at the input stage with a linear range of 800mVpp, diff followed by a super source follower and an output buffer. The T/H achieves a loss of -1.16dB in low gain mode and 0.6dB of gain in high gain mode. The circuit consumes 13.8mW at 1.2V supply and occupies an area of 0.109mm2. It achieves an ENOB of 8-9 and 8-12.7 fJ/conversion at 2.5GS/s.
