Abstract
A multi-stage device for boosting an input voltage is discussed. Each stage of the device comprises a stage of a ring oscillator and a charge pump. An oscillating signal, generated by the ring oscillator within the device, drives the charge pump in each stage of the device. The charge pumps of the stages are serially connected. A final stage of the multi-stage device is adapted to provide voltage to a load circuit. The multi-stage device is applicable for generation of different bias voltages from one or more source voltages.
