10 Hz to 10 Khz Voltage Controlled Oscillator

Posted on Feb 4, 2014

Voltage-controlled oscillator (VCO) is an oscillator that its frequency is controlled using a voltage signal. The VCO described here provide both triangular and square wave output. The control voltage can be varied between 5 mV to 5 V, to produce oscillation frequency from 10 Hz to 10 KHz. Here is the schematic diagram of the circuit: This is a sc

hematic diagram of a micropower voltage-controlled oscillator circuit. This circuit can generate square and triangle wave outputs and only need 50 µA from a single 5 V supply. This circuit consist of combination of an inexpensive quad CMOS Continue reading †’. VCO (voltage controlled oscillator) is an electronic signal generator which produce a signal that has variable frequency depends on a voltage level at its control input. Many VCO circuits are based on ramp generator to produce a variable frequency output, Continue reading †’.
