Phase-locked loop triumph

I have always had a soft spot for phase-locked loops – at least, I have since I first found out what they were. What I like about them is that they servo into the best answer for a given situation – ...

Operation of MEMS Coriolis Vibratory Gyroscopes

This article discusses the various control mechanisms for MEMS Coriolis Vibratory Gyroscopes (CVG), and how they can be applied with the commercial off-the-shelf HF2LI Lock-in Amplifier. A MEMS ...

Fully Digital Implemented Phase Locked Loop

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 ...

Unlock The Phase Locked Loop

If you want a stable oscillator, you usually think of using a crystal. The piezoelectric qualities of quartz means that it can be cut in a particular way that it will oscillate at a very precise ...

Low Power Phase-Locked Loop with VCO

The 74HC/HCT4046A are phase-locked loop (PLL) with linear voltage-controlled oscillator (VCO) CMOS device having pins suited to 4046 in a 4000B series. These devices comply to JEDEC standard no. 7A.

Lockdown project: Enter the 9046 – the ultimate ‘4046’ phase-locked loop

I had never heard of the 74HCT9046 phase-locked loop before a fortnight ago, and now I own one. To my shame, it was apparently released by Phillips (now Nexperia) around 20 years ago – that said, the ...

Tracking PLL design through the decades, part 1

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 ...

The Main Principles of Lock-in Detection

Lock-in amplifiers were invented in the 1930s [1, 2, 3] and commercialized [4] in the mid 20 th century as electrical instruments that are capable of extracting signal amplitudes and phases in ...
