ABSTRACT:
A signal sampling apparatus for generating an output signal according to an input signal is disclosed. The signal sampling system includes a sample and hold circuit and a gain controller. The sample and hold circuit is used for sampling the input signal to generate a sample signal in a sample mode, and the sample and hold circuit includes an amplifier having a gain for generating the output signal according to the sample signal in a hold mode. The gain controller is coupled to the amplifier for adjusting the gain in the sample mode.
