摘要:
A fast attack Automatic Gain Control (AGC) loop (100) having the capability to selectably shape one or more decaying current sources (242, 260) contained within an off-channel feedback loop and an on-channel feedback loop of the AGC loop by sequentially and selectively switching out weighted transistors (Tr0, Tr1, Tr2, . . . , Tr10) of a plurality of weighted current mirrors (313, 379, 453, 519) at predetermined intervals (t0, t1, t2, . . . , t10).
