This paper presents a 2.45-GHz complementary metal–oxide–semiconductor (CMOS) ultra-low-power transmitter suitable for cochlear implant application. This system will be energy self-efficient and be put in an 8 ,\times, 6 ,\times, 6 {\hbox {mm}}^{3} small volume. The entire system will be consuming less than 1 mA under 1.2 V supply for an output power range from {- 10}~{\rm dBm} to 0 dBm. Implemented in a 130 nm CMOS standard process, the first radio microphone prototype burns 1.6 mW for a {- 2}~{\rm dBm} output power.
