Voltage booster circuit with ripple control and method controlling same
A voltage booster circuit includes a primary charge pump circuit, a secondary charge pump circuit and a transistor. The primary charge pump circuit is used to convert a supply voltage into a boosted voltage in response to a clock signal. The secondary charge pump circuit is used to convert the supply voltage into a regulated voltage in response to the clock signal. The transistor is coupled to the primary charge pump circuit and the secondary charge pump circuit, and has a control terminal receiving the regulated voltage, a first terminal receiving the boosted voltage and a second terminal outputting an output voltage.
