Abstract
Techniques are provided for an integrated circuit, current loop interface that can receive and extract a high-frequency digital communication signal from a low-frequency analog current signal using a complex impedance circuit. The complex impedance circuit can allow for low input impedance at the lower frequencies of the analog current signal and high input impedance at the higher frequencies of the digital communication signal.
