Abstract :
Presents a fully integrated CMOS fast phase locked loop (PLL), based on a new wide swing differential voltage controlled oscillator (WSDVCO). The proposed PLL incorporates new simple architecture of well known PLL building blocks (a dynamic phase-frequency detector, a charge pump, an on-chip low-pass filter, a WSDVCO and a frequency divider). The present version of the WSDVCO allows one to obtain wide tuning range of 40 to 730 MHz simulated with Spectre simulator using 0.25 μm CMOS technology. The simplicity of the proposed PLL building blocks permits one to design high performance PLL
