摘要:
A receiver (100) includes a first element (110) with a signal input, a control input, a signal output, and gain steps of a first magnitude, a signal processing circuit (120-168) with a signal input coupled to the first element, and a signal output, a second element (180) that has a signal input coupled to signal processing circuit, a control input, a signal output, and gain steps of a second magnitude smaller than the first magnitude, and a controller (180) that has a control output coupled to the first element (110), a control output coupled to the second element (180), and that adjusts receiver (100) gain by changing the first element (110) gain by a first magnitude, changing the second element (180) gain by substantially an inverse first magnitude, and subsequently changing the gain of the second element (180) by steps of the second magnitude to achieve a desired gain.
