Voltage Controlled Amplifier Circuit

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

Voltage controlled amplifier circuit.

A voltage controlled amplifier can be realised by first creating a voltage controlled resistor vcr which is used to set the amplifier gain. 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. This type of circuit has many applications including audio level compression synthesizers and amplitude modulation.

A variable gain or voltage controlled amplifier is an electronic amplifier that varies its gain depending on a control voltage. It can be realized by first creating a voltage controlled resistor which is used to set the. 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. A current ilsc is inserted into this input which controls the gain of the device linerly.

A voltage amplifier circuit is a circuit that amplifies the input voltage to a higher voltage. 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. 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.
