Abstract :
A new design technique for realizing a true fully differential sample-and-hold (S/H) circuit is presented. This technique avoids the reset phase and consequently the need for a high slew rate for the operational amplifier, it therefore can be used for high-speed applications. A prototype circuit, which occupies 0.1 mm2 in a 3- mu m CMOS process, is integrated and experimental results are presented.
