An Inductively Coupled Power and Data Link with Self-referenced ASK Demodulator and Wide-range LDO for Bio-implantable Devices

This paper describes a neural stimulation system that employs an inductive coupling link to transfer power and data wirelessly. For the reliable data and power delivery, a self–referenced amplitude-shift keying (ASK) demodulator and a wide-range voltage regulator are suggested and implemented in the...

Description
Summary:This paper describes a neural stimulation system that employs an inductive coupling link to transfer power and data wirelessly. For the reliable data and power delivery, a self–referenced amplitude-shift keying (ASK) demodulator and a wide-range voltage regulator are suggested and implemented in the proposed stimulator system. The prototype fabricated in 0.35 um BCD process successfully transferred 1.2 Kbps data bi-directionally while supplying 4.5 mW power to internal MCU and stimulation block. KCI Citation Count: 3
