Embodiments of the present disclosure provide an enhanced phase-locked loop (PLL) circuit and an enhanced charge pump circuit used for various applications, including high-speed data clock generation for complex integrated circuit (IC) designs. The disclosed PLL circuit and charge pump circuit enable significant power and supply current reduction, improved circuit reliability; reduced self-heating and electro-migration risk, and enable use of lower power operational amplifiers with the operational amplifiers driving high impedance nodes.
