Abstract
A semiconductor device includes a receiver system having a first set of amplifiers, a second set of amplifiers, and an automatic gain control (AGC) module to receive first high and low detection signals from a first peak detector, and receive second high and low detection signals from a second peak detector. When the first high detection signal is set, a step decrease in at least one of a first gain control signal and a second gain control signal is taken. When the first high detection signal is not set and the second high detection signal is set, a second step decrease in at least one of the first gain control signal and the second gain control signal is taken. The first gain control signal is used in the first set of amplifiers. The second gain control signal is used in the second set of amplifiers.
