Title Proper : CMOS AUTO-RANGING PHASE-LOCKED LOOP INTEGRATED CIRCUITS FOR FREQUENCY SYNTHESIZERS AND CLOCK RECOVERY CIRCUITS
Note : This document is digital این مدرک بصورت الکترونیکی می باشد
Abstract : auto-ranging phase-locked loop (PLL) circuit has been fabricated using a MpmComplementary Metal-Oxide-Silicon (CMOS) technology. This circuit is equipped witha sel f-sensedhdj usted capacity in response to a large. fast frequency switching input.and has good immunity to temperature, processing. and supply voltage variations. Theauto-ranging PLL technique has been successFully applied to a 644 1 6 MHz frequencysynthesizer and a 15 1-600 MHz nonreturn-to-zero (NRZ) clock recovery circuit. Thefrequency synthesizer uses a coarse-steering frequency comparator to coarse tune theoscillator frequency within an adequate range where the conventional PLL continues andcompletes the final acquisition. The clock recovery circuit employs a bit-rate detection......-....,....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
