Ultra-Low-Power Audio Communication System for Cochlear Implant Application
In this paper, we propose a 2.45 GHz CMOS transceiver with an ultralow power transmitter for cochlear implant application. This transmitter will be put in a 8 × 6 × 6 mm3 small volume. Implemented in a 130 nm CMOS standard process, it will be consuming about 3
mA under 1.2 V supply for an output power around –20 dBm. The receiver, designed with commercial components, is also presented and can offer, at the end of this paper, a system validation for this wireless microphone at 2.45 GHz.

- The electronic systems that can operate with very low power are of great technological interest. The growing research activity in the field of low power electronics requires a forum for rapid dissemination of important results: Journal of Low Power Electronics (JOLPE) is that international forum which offers scientists and engineers timely, peer-reviewed research in this field.
