Abstract

A 2-Mbps 400-MHz On-Off Keying (OOK) transceiver implemented in 0.18-μm CMOS technology for implantable epilepsy devices is presented. The proposed transceiver is composed of voltage control oscillator (VCO) and OOK function generator in the transmitter part, and new current-mode envelope detector and cascaded gain amplifiers in the receiver part. The fabricated transmitter has power consumption of 0.84 mW and energy consumption of 0.42 nJ per bit. The fabricated receiver has power consumption of 0.59 mW and energy consumption of 0.295 nJ per bit. The sensitivity of receiver is 45 dBm.
