A radio receiver and method of operating the same are disclosed. In one embodiment, the radio receiver may include a RF receive path configured to convey a first radio signal within a first band to a radio tuning circuit. The RF receive path may be controllable using a first AGC circuit. The radio receiver may also include a loop-through path configured to convey a second radio signal within a second band between an input and an output of the radio receiver. The second band may be different from the first band. The loop-through path may be controllable using a second AGC circuit.

Receiver chip with multiple independent loop-through paths

Systems and methods for controlling operation of an integrated circuit by applying below ground voltage to one or more pins of the integrated circuit, and in which the application of a below ground pin voltage may be employed as an initiator of (or condition for) a given mode of circuit operation in a manner that prevents the inadvertent initiation of the given mode of operation that may otherwise occur due to accidental application of an above ground voltage to one or more pins of the integrated circuit.
