Voltage Controlled Amplifier Circuit

Vcrs manufactured in this way can be obtained as.

Voltage controlled amplifier circuit.

This voltage controlled amplifier circuit is simply an op amp having an additional input at pin 5. The amplifier can achieve an 80 db dynamic control range with less than 0 2. A simple linear voltage controlled amplifier can be constructed with one op amp and two jfets see the figure. A variable gain or voltage controlled amplifier is an electronic amplifier that varies its gain depending on a control voltage.

A voltage amplifier circuit is a circuit that amplifies the input voltage to a higher voltage. It can be realized by first creating a voltage controlled resistor which is used to set the. An amplifier electronic amplifier or informally amp is an electronic device that can increase the power of a signal a time varying voltage or current it is a two port electronic circuit that uses electric power from a power supply to increase the amplitude of a signal applied to its input terminals producing a proportionally greater amplitude signal at its output. How to build a voltage controlled oscillator circuit with a 4046 chip.

The vcr is one of the numerous interesting circuit elements that can be produced by using a jfet junction field effect transistor with simple biasing. Thus by inserting an audio signal 10 mv within pin 2 and 3 and with controlling the current on pin 5 the amount of the signal output pin 6 is controlled. This type of circuit has many applications including audio level compression synthesizers and amplitude modulation.
