At the heart of a clocking device is the phased-locked loop (PLL). A key part of the PLL is the loop filter, which converts correction currents from the PLL charge pump into a control voltage for the ...

A phase-locked loop (PLL) is a feedback system that combines a voltage-controlled oscillator (VCO) and a phase detector in such a way that the oscillator signal tracks an applied frequency or ...

The PLL circuit shown in Figure 1 uses a 13 GHz Fractional-N synthesizer, wideband active loop filter and VCO, and has a phase settling time of less than 5 μs to within 5° for a 200 MHz frequency jump ...

The demand for analog and mixed-signal-based integrated circuits (ICs) has surged due to the increasing reliance on electronic-based applications across industries. As the world transitions to more ...

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 ...

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, ...
