Radiation-hardened phase-locked loop (PLL) circuits represent a critical advancement in safeguarding electronic systems against the deleterious effects of ionising radiation. These circuits are ...

The HEF4046B is a phase-locked loop circuit that contains a linear voltage-controlled oscillator (VCO) and two discrete phase comparators that has a common signal input amplifier and a common ...

One of the most challenging tasks in analog circuit design is to adapt a functional block to ever new CMOS process technology. For digital circuits the number of gates per square mm approx. doubles ...

TI offers clock and timer solutions with Phase Lock Loops (PLLs) including PLL clock buffers, PLL clock synthesizers, PLL based multipliers, zero delay PLL clock drivers and more. Whether you need ...

In this paper an All Digital phase locked loop is proposed. This PLL can accomplish faster phase lock. Additionally, the functions of frequency comparator and phase detector have been improved and are ...

But taking a voltage-controlled oscillator at 100 MHz (nominal) and dividing its output by 100 will give you a signal you can lock to a 1 MHz crystal oscillator which is, of course, trivial to build.

…which would take a pulse-width-modulated waveform at any frequency, and produce a signal with exactly the same mark/space ratio, but at a nominated frequency (see ‘Why might this be useful?’ below).

A comparator is an electronic component that outputs different voltage results at the output by comparing the magnitude of the current or voltage at the two inputs. This article describes the ...
