A phase-frequency detector and a charge pump design for PLL applications
An improved phase frequency detector (PFD) and a novel charge pump (CP) for phase locked loop (PLL) applications are presented. Implemented in a CMOS 0.13μm technology, the PFD and the CP dissipate 3.73mW and a 460μW DC power from a 1V supply, respectively. The occupied chip area of the PFD is 68×24μm2, and that of the CP is 68×23μm 2. With a spurious free dynamic range of a 80dBc, a phase noise of a -95dBc/Hz at 100kHz offset, a low power and a small layout area the presented PFD and CP are suitable for integrated radio applications operating between 2.4GHz and 10GHz, such as 802.11 and WiMax for example.
