Abstract
An input signal to be sampled by a sample and hold circuit is amplified separately by two amplifiers. The output of the first amplifier is provided to a boost circuit to maintain the impedance of a sampling switch contained in a signal dependent boost switch substantially constant. The output of the second amplifier is sampled via the sampling switch, and the sample is stored in a storage element. The second amplifier drives a reduced load, and may be implemented as a low bandwidth, low power amplifier to reduce overall power consumption.
