Abstract
A track-and-hold circuit includes a bootstrapped clock generator and a track-and-hold unit. The bootstrapped clock generator receives an input voltage signal and generates a sampling control signal having a voltage level lower than or equal to a level of a power supply voltage by maintaining an initial level of a boost capacitor voltage at a level lower than the level of the power supply voltage. The boost capacitor voltage is a voltage that is charged across a boost capacitor included in the bootstrapped clock generator and the sampling control signal is generated based on a clock signal. The track-and-hold unit samples and holds the input voltage signal in response to the sampling control signal to generate a sampled signal.
