Abstract
A fully differential sample-and-hold (S/H) circuit using double-sampling is presented. Compared to a conventional S/H configuration with a similar opamp the double-sampling gives a factor of two increase in the sampling rate while maintaining comparable power consumption. The circuit is designed in 0.5 μm CMOS technology. Measurements show 10 bit operation up to the Nyquist frequency at the sampling rate of 220 MS/s with 25 mW at 3 V power dissipation
