Abstract
A digital step attenuator for automatic gain control in a transceiver front-end. The digital step attenuator includes a series path coupled between an input port and an output port, a plurality of series shunt switches coupled in parallel to the series path, and a plurality of parallel paths coupled to the series path in parallel. The series path includes a plurality of series resistors coupled in series. Each series shunt switch is for by-passing a different set of one or more series resistors. Each parallel path includes a parallel resistor and a parallel shunt switch, and each parallel path is coupled to either the input port, the output port, or an internal node between two adjacent series resistors, in parallel. A plurality of different π-attenuators with a different topology are formed by selectively controlling the series shunt switches and the parallel shunt switches.
