Voltage Controlled Amplifier Circuit

The amplifier can achieve an 80 db dynamic control range with less than 0 2.

Voltage controlled amplifier circuit.

Vcrs manufactured in this way can be obtained as. This voltage controlled amplifier circuit is simply an op amp having an additional input at pin 5. How to build a voltage controlled oscillator circuit with a 4046 chip. So for example if we input 1v into the circuit we can get 10v as output if we set the circuit for a gain of 10.

A voltage controlled amplifier can be realised by first creating a voltage controlled resistor vcr which is used to set the amplifier gain. It can be realized by first creating a voltage controlled resistor which is used to set the. A voltage amplifier circuit is a circuit that amplifies the input voltage to a higher voltage. 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.

A simple linear voltage controlled amplifier can be constructed with one op amp and two jfets see the figure. A current ilsc is inserted into this input which controls the gain of the device linerly. 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.
