Resumen
Descripción
A charge pump circuit capable of operating at different switching speed is presented. The switching speed control is added to a typical charge pump circuit by mean of enable switches which allow drive different currents. Charge pump circuit is implemented in AMI 0.5µm CMOS technology. Simulations were performed using Spectre from CadenceTM. Simulation results show clearly an increase in the slope of charging or discharging curves of load capacitor during the pumping-up and pumping-down phases.
