Automatic Gain Control (AGC) circuits
The main objective of this paper is to provide the hypothetical reader with a deep insight of the theory and design of AGC circuits ranging from audio to RF applications. We will begin studying the control
Automatic gain control
In a typical receiver, the AGC feedback control signal is usually taken from the detector stage and applied to control the gain of the IF or RF amplifier stages.
CN-0390 (Rev. 0)
The automatic gain control (AGC) circuit is useful in multiple applications such as amplitude stabilization of a synthesizer, controlling output power in a transmitter, or optimizing dynamic range in a receiver.
5. Receiver Gain and AGC
Instead, receiver designers implement an adjustable gain amplifier using one or more fixed gain amplifiers and one or more variable attenuators (e.g., digital attenuators).
How Automatic Gain Control (AGC) Works
In principle, an AGC is a feedback control system that drives the amplitude error to zero in an iterative fashion. This establishes, on average, a constant signal amplitude at the start of the
