Apparatus and method for automatic gain control |
摘要 |
An apparatus and an associated method for automatic gain control (AGC) are provided to improve the ability to lock effective signal power when interference exists, thereby upgrading the receiver performance of a communication system. The apparatus includes a variable-gain circuit for adjusting the power level of an input signal. The apparatus also includes a gain adjustment circuit and a target value adjustment circuit. The gain adjustment circuit is for adjusting the gain of the variable-gain circuit according to the adjusted input signal and a target value, while the target value adjustment is for dynamically adjusting the target value according to the strength of the adjusted input signal.
