Abstract
An integrated transient voltage pulse multiplier is used to increase the voltage to the gates of control switches in a low voltage circuit. The increased conductance of the control switches permits a reduction in gate width, reducing parasitic charge injection and capacitive feedthrough. A low distortion switched capacitor filter utilizes two transient voltage pulse multipliers to increase the voltage of non-overlapping clock signals. The switched capacitor filter is operative at a power supply voltage of less than 1.5 volts.
