ABSTRACT:
A CMOS regulated complementary charge pump circuit uses imbalanced current regulation and symmetrical capacitive loading of input signals to provide a proportional response and high sensitivity at small phase differences. The charge pump is suitable for operation at very high frequencies, and therefore finds applications in delay-locked and phase-locked loops used to regenerate system clock signals within VLSI circuits. The use of current limiting devices in the switch pass gates permits a balancing of the capacitive loads presented to the input signals. Adjustable capacitors permit the elimination of a static phase offset at a zero operating point.
