Abstract

According to an embodiment, an interface circuit includes a current replicator and a receiver. The current replicator includes a power terminal coupled to a first reference node, an output terminal configured to output a signal proportional to a signal received from a transducer, and an interface terminal coupled to the transducer. Using a single interface terminal, the current replicator may be configured to provide power to the transducer and receive output signals from the transducer. The receiver may include a first input terminal coupled to the output terminal, a second input terminal coupled to a second reference node, and a current converter circuit coupled to the first input terminal.
