A new wideband ring voltage-controlled oscillator (VOC) was proposed by UNIST undergraduate student, Seyeon Yoo with the the research work published in IEEE Microwave and Wireless Components Letters. ...

We think of crystals as the gold standard of frequency generation. However, if you want real precision, you need something either better than a crystal or something that will correct for tiny errors — ...

UMC, a world leading semiconductor foundry, today announced it has fabricated a Voltage-Controlled Oscillator (VCO) with a record-setting fundamental operating frequency of 105-GHz using its 0.13um ...

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 ...

Editor’s Note: This DI is a two-part series. Part 1 shows how to make an oscillator with a pitch that is proportional to a control voltage. Part 2 shows how to modify the circuit for use with higher ...

The charge pump has many applications. While we generally think of power supply applications, it is also very useful in this voltage controlled oscillator. This VCO has a number of useful features ...

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 ...
