A Novel Area Efficient Inductorless Super-Regenerative Receiver Front-End for Medical Brain Implants

A novel area and energy efficient inductorless super-regenerative receiver (SRR) is proposed for medical brain implants dedicated to epilepsy monitoring and treatment. The proposed SRR was fabricated in UMC CMOS 180nm technology. The SRR occupies only 0.072mm
²
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 4 Mbps. 3.22 nJ/b energy efficiency is obtained with 12.9mW power consumption from a 1.8V power supply.
