| Summary: | 博士 === 國立中正大學 === 電機工程研究所 === 102 === A programmable real-time detection and stimulation system is presented and integrated on a chip with smart powering management, immediate neural signal acquisition, and wireless rechargeable system. A system controller with parity checking handles the adjustable stimulus parameters for the stimulated objective. In this dissertation, the rat’s intra-cardiac electrogram is employed as the stimulated model in the animal study, and is sensed by a low-voltage and low-power monitoring analog front end. The power management unit, which includes a rectifier, battery charging and detection, and a regulator, is utilized for the power and supply control of the implanted circuits. The stimulation data and required clock are extracted by a phase-locked-loop-based (PLL) phase shift keying (PSK) demodulator from an inductive AC signal. The full implantable chip that consumes only 48µW is fabricated in a TSMC 0.35 μm 2P4M standard CMOS process to perform the monitoring and pacing functions with inductively powered communication. An in vivo experimentation using Sprague-Dawley (SD) rats is studied at the end of this dissertation to demonstrate the performance of proposed system.
