摘要	This paper proposes a wireless bimodal 16-channel current-controlled neural stimulation IC. Bipolar biphasic current-controlled stimulations are generated with wirelessly controlled pulse widths, amplitudes, and inter-phase intervals. The stimulation module utilizes a transistor-stacked topology to achieve a 12-V voltage compliance while being fabricated in a low-voltage CMOS technology. Wireless signals at 13.56 MHz encoded with either Manchester coding schemes can be received to generate the system clock and the payload data. A novel demodulation scheme is proposed, which supports bimodal operations, i.e., single-channel stimulation at ultra-high frequencies and simultaneous multi-channel neural modulation. The IC is fabricated in a 0.18-μm 1.8-V/3.3-V CMOS technology. The idle mode power consumptions of the IC and the wireless stimulation system are approximately 9 μW and 132 μW, respectively. Measurement results show the successful operation of the system and verify the high-voltage reliability of the IC.
