Operational amplifiers used in PLL charge pump circuits


In this paper, the detailed design procedure for two operational amplifiers (OP-Amp) used in charge pumps (CP) is presented. Such procedure, which is from system-level specifications to circuit-level requirements, provides a general methodology for OP-Amp design in CP. The design was simulated in a 0.18µm CMOS process and occupies a layout area of… (More)
