Abstract
A charge pump circuit includes a delay circuit, a transistor, and a capacitor. The charge pump receives an input signal and outputs an output signal. The delay circuit receives a first signal based on the input signal and outputs a first delayed signal. The transistor includes a gate, a first channel node, and a second channel node. The first channel node receives the first signal. The second channel node is connected to the output and to a first plate of the capacitor. A second plate of the capacitor receives a second signal based on the first delayed signal. The charge pump circuit is adapted to operate such that the voltage range of the output signal is greater than the voltage range of the input signal.
