In this session of Logic Noise, we’ll be playing around with the voltage-controlled oscillator from a 4046 phase-locked loop chip, and using it to make “musical” pitches. It&#8217… ...

When the output of U1A reaches 6V, the output of comparator U1B switches and quickly discharges (pumps or dumps) C2 into C1 via D1. This is the basic charge pump circuit. This reduces the voltage ...

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.

The gain of this operational amplifier is voltage controlled and can be adjusted by voltage variation through P2. This potentiometer must be adjusted in such way that the wien bridged oscillator ...

HSINCHU, Taiwan--Feb. 21, 2006--UMC (NYSE:UMC)(TSE:2303), a world leading semiconductor foundry, today announced that it has fabricated a push-push Voltage-Controlled Oscillator (VCO) with an ...

Teledyne e2v HiRel announces the availability of a pair of Voltage Controlled Oscillators (VCOs) with low phase noise performance for low earth orbit ...

FSK/PSK modulator circuits usually employ analogue components such as VCO (voltage control oscillator), RF Mixer, and Level-shifter, with limited frequency range and whose performance drifts with ...
