Abstract
A multimode fast attack automatic gain control (AGC) circuit (,) includes an analog feedback loop and a digital feedback loop. The analog feedback loop is switched into the amplifier stage (,) by a first switch (,) when dynamic control of the gain attenuation is desired. The digital feedback loop is switched into the amplifier stage when attenuation is to be adjusted periodically, such as between sequentially received time slots in a time division multiple access (TDMA) mode of communication.
