Abstract
A sample-and-hold amplifier (400) having a sample phase of operation and a hold phase of operation. The sample-and-hold amplifier comprising one or more sampling components (404, 406) 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 (402) configured to pre-charge the output (416, 418) of the sample-and-hold amplifier (400) during the sample phase of operation, and buffer the sampled input signal during the hold phase of operation.
Claims17
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.
A method of operating a sample-and-hold amplifier, the sample-and-hold amplifier comprising an amplifier having an output that is connected to an output of the sample-and-hold amplifier, the method comprising:
- sampling input signals during a sample phase of operation;
- providing sampled input signals during a hold phase of operation;
- and
- using the amplifier 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.
