Patent ID: 8390372

Claim:
A sample-and-hold amplifier having a sample phase of operation and a hold phase of operation, the sample-and-hold amplifier comprising: at least one sampling component configured to sample input signals during the sample phase of operation, and provide sampled input signals during the hold phase of operation; and an amplifier having an output that is connected to an output of the sample-and-hold amplifier, wherein the amplifier is configured to: provide an output signal to pre-charge the output of the sample-and-hold amplifier during the sample phase of operation, and buffer the sampled input signal during the hold phase of operation, wherein one of the at least one sampling component includes a first terminal and a second terminal, wherein the first terminal is connected to the amplifier through a first switch, and wherein the second terminal is connected to the output of the sample-and-hold amplifier through a second switch.
