Abstract
An analog-to-digital converter includes a sample hold circuit configured to receive an analog input signal based on an operating mode, the operating mode being one of at least two modes including a sample mode and a hold mode. The sample hold circuit includes a first transistor including a control terminal and a first terminal, the first transistor configured to receive a control signal via the control terminal and receive the analog input signal via the first terminal. The analog-to-digital converter further includes a bootstrap switch operationally connected to the control terminal and the first terminal of the first transistor, the bootstrap switch configured to form a first current path from a power source based on the analog input signal and a boosted voltage of the control terminal of the first transistor in the sample mode, the control terminal bing along the first current path in the sample mode.
