摘要
A new technique for realizing a very-high-speed low-power low-voltage CMOs fully differential track-and-hold circuit with low hold pedestal is presented. To achieve high sampling linearity the circuit utilizes improved bootstrapped input switch. The fully differential design relaxes the trade-off between sampling speed and the sampling precision. The circuit design of major building blocks is described in detailed. A prototype circuit in a 0.35-mu m CMOs process is integrated and experimental results are presented.
