Webxn--webducation-dbb.com WebJul 4, 2015 · This paper introduces a modified design of Phase frequency detector (PFD) with reduced dead zone and improved charge pump (CP) with reduced current mismatch for a Phase Locked Loop (PLL). Three modified PFD circuits are proposed, designed, simulated, and the results are analyzed considering dead zone as a constraint.

WebThe design methodology and the test results of a low-voltage differential charge pump structure for phase-locked loop (PLL) applications are presented. The structure is composed of two charge/discharge blocks, a replica bias circuit, and a sampled data common-mode feedback (CMFB) block that adjusts the pump-up current for symmetrical … Webloop bandwidth to be doubled from 20kHz to 40kHz, so that close-in noise floor is 6dB lower and switching time is halved. Referring to the block diagram in Figure 1, the frequency synthesizer implemented in this work is based on a charge-pump phase-locked loop architecture. The 4GHz VCO directly drives a dual-modulus divide-by-64/65 prescaler. fm stations transmitter locations
