High Data Rate FinFET On-Off Keying Transmitter for Wireless Capsule Endoscopy

Abstract

Wireless capsule endoscopy (WCE) is a painless diagnostic tool used by the physicians for endoscopic examination of the gastrointestinal track. The performance of the existing WCE systems is limited by high power consumption and low data rate transmission. In this paper, a 144 MHz FinFET On-Off Keying (OOK) transmitter is designed and integrated with a class-E power amplifier. It is implemented and simulated using 16 nm FinFET Predictive Technology Models. The proposed transmitter can achieve the data rate of 33 Mbps with average power consumption of 1.04 mW from a 0.85 V power supply in the simulation. This design outperforms the current state-of-the-art designs.

Design and Implementation of High Performance PPSK demodulator in Biomedical Implant

“…Major sub block is Back telemetry pretend to monitor the internal unit, electrode unit conditions & neural responses. An ASIC chip with power ampli er [10], error frees decoder/demodulator [11] and Analog to Digital Converter (ADC) is integrated for internal feedback purpose. However, propagating the signal impulse in mv range into the body is crucial task.…”
