1. A circuit for communicating a digital baseband signal, comprising:
- first receiver circuitry for providing first application data;
second receiver circuitry for providing second application data;
a frame buffer configured to selectively receive the first application data or the second application data as a function of a control signal, and to facilitate the presentation of the selectively received data to a digital baseband processor via a common digital interface.

Abstract
In one embodiment, a circuit can selectively adjust a current for driving a load. The circuit includes a sensor configured to measure a magnetic field associated with the current and provide a sensor voltage representative thereof. A control circuit is configured to selectively adjust the current as a function of the sensor voltage and a time-varying voltage threshold. Other methods and systems are also disclosed.
