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

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 144MHz FinFET On-Off Keying (OOK) transmitter is designed and integrated with a class-E power amplifier. It is implemented and simulated using 16nm FinFET Predictive Technology Models. The proposed transmitter can achieve the data rate of 33Mbps with average power consumption of 1.04mWfrom a 0.85V power supply in the simulation. This design outperforms the current state-of-the-art designs
