Abstract

A voltage boosting circuit with a closed-loop control mechanism and a controllable slew rate. A tracking capacitor and a control current form the closed-loop and are used to adjust the slew rate of the boosting circuit. The closed-loop control and adjustable slew rate improve the accuracy and predictability of the boosting circuit's final boosted output voltage.
