Abstract
A current mode receiver front end for a radio device converts a received signal into a current mode signal and applies automatic gain control by both shunting current of the current mode signal and providing an adjustable series resistance that further adjust the current level of the current mode signal that is output by the receiver front end. The shunt and series circuits can be controlled by a digital control word whose value represent a decibel value of adjustment, and which is used to drive the shunt and series circuits to achieve both coarse and fine adjustment of the current mode signal.
