Abstract
The present invention discloses a regulator system (,) for regulating the output current and voltage (Vout) of a charge pump circuit (,). It is observed that the output current and voltage (Vout) of a charge pump circuit (,) can be regulated by varying the amplitude and frequency of a set of clock signals (modulated clocks). The present invention comprises means (decoders,AM, FM units) for generating a set of control signals (VAD,-VFDn) as the function of the output current and voltage (Vout). The set of control signals (VAD,-VFDn) is coupled to a clock signal generation circuit (,) that generates a set of clock signals (modulated clocks) having a magnitude and a frequency depending on this set of at least one control signal. This set of clock signals (modulated clocks) is then used to drive the charge pump circuit (,). It is found that this regulator circuit (,) consumes less power than prior art regulator circuits.
