Optimization Techniques for Source Follower Based Track-and-Hold Circuit for High Speed Wireless Communication

Since the current demand for highneedfor track and hold amplifiers (T&H) operating at RF frequencies. Acircuit is the key element in any modern wideband data acquisition system. Applications like a cableor a broad variety of different radio standards require high processing speeds with high resolution. Thetrack-and-hold (T&H) circuit is a fundamental block for analogallows most dynamic errors of A/D converters to be reduced, especially those showing up when usinghigh frequency input signals. Having a wideband and precise acquisition systemtoday’s trend towards multi-standard flexible radios, with as much signal processing as possible indigital domain. This work investigates effect of various design schemes and circuit topology for trackand-hold circuit to achieve acceptable linearly, high slew rate, low power consumption and low noise
