Abstract :
A prototype of a one-time implantable spinal cord stimulation (SCS) system using wireless power and data transmission techniques is presented in this paper. The proposed novel ASK demodulator attains high demodulation performance and small area consumption without using any resistor and capacitor. The proposed SCS system utilizes many power saving schemes to reduce the power dissipation, e.g., dual supply voltages on chip, high voltage impulse generation using a small current, etc. The system on chip (SOC) is physically implemented on silicon and integrated in the implant as the system controller. Compared with existing commercial products, the proposed SCS system attains better flexibility and longer operation time.
