N2 - We demonstrate an inductively powered, orthogonal current-reuse multi-channel amplifier for power-efficient neural recording. The power rectifier uses the input swing as a self-synchronous charge pump, making it a fully passive, full-wave ladder rectifier. The rectifier supplies 10.37μW at 1.224V to the multi-channel amplifier, which includes bias generation. The prototype device is fabricated in a TSMC 65nm CMOS process, with an active area of 0.107mm2. The maximum measured power conversion efficiency (PCE) is 16.58% with a 184mV input amplitude.
