An area efficient inductorless super-regenerative receiver front-end for biomedical implant devices

Wearable and implantable medical devices are of great importance in diagnosis and treatment as they provide continuous monitoring and data collection. Considering the comfort of the patient and ease-of-operation, these devices require wireless data transmission. In this work, a novel area and energy efficient inductorless super-regenerative receiver (SRR) is proposed for medical implants dedicated to patient monitoring and treatment. The proposed SRR was fabricated in UMC CMOS 180 nm technology. The SRR occupies only 0.072mm2 which corresponds to an order of magnitude area reduction compared to the state-of-the-art. The SRR achieves −70dBm sensitivity and the highest data rate is 4Mbps. 3.22nJ/b energy efficiency is obtained with 12.9mW power consumption from a 1.8V power supply.
