Abstract
A circuit for generating a boosted voltage includes a logic portion and a switching portion. The logic portion is coupled to receive a clock signal and, in response thereto, provides control signals to an associated switching circuit. During a first portion of the clock signal cycle, the switching circuit pulls an output terminal of the circuit to the supply voltage. During a second portion of the clock signal cycle, the switching circuit utilizes a bootstrap capacitor to boost the output terminal of the circuit to approximately twice the supply voltage, while isolating the output terminal from the supply voltage.
