PLLs (phase-locked loops) are common analogcircuits in SOCs (systems on chips). Almost allSOCs with a clock rate greater than 30 MHzuse a PLL for frequency synthesis. However, a“one-size-fits-all” PLL ...

Abstract: This paper describes a Fractional-N Phase Locked Loop (PLL) for multi-phase (=M) clock generation by reducing capacitor area. The M-phase clocks from the Voltage Controlled Ring Oscillator ...

Clock signals provide reference timing to every integrated circuit and electrical system. Consumer applications typically use simple quartz crystals for reference clock generation. Other applications, ...

Abstract: A sub-THz phase-locked loop (PLL) with a power-gating injection-locked frequency multiplier-based phase detector and extended loop bandwidth was designed to achieve ultralow jitter ...

A PLL (phase-locked loop) is perhaps the most widely used analog circuit in SOCs (system-on-a-chip). Almost all SOCs with a clock rate over 30MHz use a PLL for frequency synthesis. Most SOCs use more ...

Phase-locked loops (PLLs) are commonplace in applications like cellular phones, wireless transceivers, and Global Positioning Systems. Despite their familiarity to systems engineers, however, PLLs ...

PLLs (phase-locked loops) are among the most commontypes of analog/mixed-signal circuits on today’sSOC (system-on-chip) ICs. PLLs are essential companionsto the digital-logic circuits and processorson ...

An important task for a digital communications receiver is to remove any frequency/phase offsets that might exist between the transmitter and receiver oscillators. Designers typically implement a ...
