摘要： A coarse reference ladder provides a plurality of coarse references. A coarse ADC receives an input voltage. The coarse ADC performs a first comparison of the input voltage and the plurality of coarse references and outputs a coarse output. A switch matrix is configured to close a switch based on the coarse output. An input line corresponding to a coarse reference is coupled to the switch matrix. The input line is precharged to the input voltage. The input line settles from the precharged input voltage to the coarse reference. A fine reference ladder provides a plurality of fine references based on the coarse reference. A fine ADC receives the input voltage and performs a second comparison of the input voltage and the plurality of fine references and outputs a fine output. Logic outputs a digital output for the input voltage based on the coarse output and the fine output.

摘要： Aspects of the disclosure provide a sampling circuit with reduced sampling distortions. The sampling circuit can include a switch and a first driving module configured to drive a first signal in response to an input signal onto a first channel terminal of the switch. The sampling circuit also can include a bootstrap module coupled to a control terminal of the switch and a second driving module coupled to the bootstrap module. The second driving module can be configured to 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 based on the input signal for turning on the switch and causing an output voltage on a second channel terminal of the switch to track the first signal on the first channel terminal of the switch.

摘要： 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.
