Abstract :
This paper will describe a veryhigh frequency (VHF) sample and hold (S&H) circuit which operates at a 120-lMHz sampling rate and is intended to drive a microwave carrier, gray-code analog-to-digital converter`. The 120-MHz sampling rate is ten times faster than that obtainable by the best previously reported system2. through a dual-diode transmission gate. When the gate The input signal is sampled by charging a capacitor is opened, the capacitor holds the output voltage constant than 0.5 ns and the holding time is 7.8 ns.until the next sampling period.
