A Precision Monolithic Sample-and-hold For Video Analog-to-digital Converters

A precision monolithic sample-and-hold (S/H) design replaces hybrid S/H circuits used in 12- to 14b-resolution analog-todigital converters with sampling frequencies up to 40MS/s. The circuit has demonstrated a sampled-mode harmonic distortion performance which is believed to exceed that of comparable monolithic devices, and which rivals that of state-of-the art hybrid implementations.
