Abstract :
Bootstrapped switches are used in a variety of applications such as pipelined analog-to-digital converters and high voltage switches, and drivers. This paper proposes a novel bootstrapped switching scheme for rail-to-rail sampling circuit. The implemented switch using new scheme can sample full-spread (0-5 V) signals under 5 V supplies. The new switch well eliminates the standard CMOS bulk effect, and performs a SNR of 87 dB at 10 MHz sampling frequency with an input signal of 1 MHz bandwidth.
