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. ...

Back in the days when an integrated circuit meant a simple but expensive device such as a 741 or a 555, most electronics ...

Fig 1. This Pierce-series resonant oscillator can reliably start at supply voltages as low as 2.4 V. It also draws very low current, ensuring long battery life. Fig 2. An oscilloscope photo shows the ...

Voltage-controlled oscillator is the generator that can be tuned over a wide range of frequencies by applying a control voltage to it. This structure ...

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 ...

Circuit VR is where we talk about a circuit and examine how it works in simulation with LT Spice. This time we are looking at a common low-frequency oscillator known as the Wien bridge oscillator.

This 1 Hz and 2Hz generator or oscillator is built with 4060 as an oscillator and a 14 bits counter. To obtain a 1Hz signal after 4060 we use 1/2 4013. This circuit provides a rectangular voltage with ...

Designed to control the frequency of crystal oscillator circuits, the 3022 series of high-ratio, hyperabrupt varactor tuning diodes is designed to deliver a dc bias control voltage from -0.3V to -4V.

Superconducting circuits, which have zero electrical resistance, could enable the development of electronic components that are significantly more energy-efficient than most chips used today.
