Abstract
Aspects of the disclosure provide a sampling circuit with reduced sampling distortions. The sampling circuit can include a switch having a control terminal, a first channel terminal and a second channel terminal. Further, the sampling circuit can include a first driving module configured to receive an input signal and drive a first signal in response to the input signal onto the first channel terminal of the switch. In addition, the sampling circuit can include a bootstrap module coupled to the control terminal of the switch and a second driving module coupled to the bootstrap module. The second driving module can be configured to receive the input signal and drive a second signal in response to the input signal to the bootstrap module, such that the bootstrap module can vary a control voltage on the control terminal of the switch based on the input signal for turning on the switch in a track-mode and causing an output voltage on the second channel terminal of the switch to track the first signal on the first channel terminal of the switch.
