More Information
Summary:An ultrasonic power/data telemetry and a neural stimulator are presented. An on-off keying with pulse modulation is adopted for ultrasonic signal transmission. The ultrasonic power is used to charge a battery. The ultrasonic data are used for neural stimulation, and an animal study is also demonstrated. The range of the stimulation current is 0-640 μA. The frequency of the stimulation current pulse is from 60 to 265 Hz. This ultrasonic power/data telemetry with a neural stimulator is fabricated in a 0.35- μm CMOS technology. It occupies the area of 4.4 mm 2 . The total power dissipation is 2 mW with a stimulation current of 140 μA and a stimulation frequency of 265 Hz.
