Since the current demand for highneed for track and hold amplifiers (T&H) operating at RF frequencies.A circuit is the key element in any modern wideband data acquisition system.Applications like a cable or a broad variety of different radio standards require high processing speeds with high resolution.The track-and-hold (T&H) circuit is a fundamental block for analog allows most dynamic errors of A/D converters to be reduced, especially those showing up when using high frequency input signals.Having a wideband and precise acquisition system today's trend towards multi-standard flexible radios, with as much signal processing as possible in digital domain.This work investigates effect of various design schemes and circuit topology for track and-hold circuit to achieve acceptable linearly, high slew rate, low power consumption and low noise KEYWORDS Track and Hold Circuit, Low Power Consumption, Slew Rate, Analog to Digital Converter
