- Abstract
- In this paper, the proposed AGC circuit is designed to adjust the strength of the received signal to a near constant optimum power level within the dynamic range of various signal processing components in the received signal path. Moreover, it can be used to dynamically control the gain of the received signal with residual DC offset and large variations caused by multi-path fading with time and frequency offset in order to ensure timely gain control for the received signal and provide reliable transmission with stable gain.
