Abstract:
A charge pump for use in a Phase Locked Loop/Delay Locked Loop minimizes static phase error through the use of an operational amplifier. The charge pump further includes a pull-up circuit and a pull-down circuit coupled to the operational amplifier. The operational amplifier also mitigates the effects of low power supply voltage.
