A 350 $\mu$W CMOS MSK Transmitter and 400 $\mu$W OOK Super-Regenerative Receiver for Medical Implant Communications

A 350μW CMOS MSK Transmitter and 400μW OOK Super-Regenerative Receiver for Medical Implant Communications

A 350μW MSK direct modulation transmitter and a 400μW OOK super-regenerative receiver (SRR) are implemented in 90nm CMOS technology. The transceiver tunes 24MHz in frequency steps smaller than 2kHz and is designed to meet the specifications of the Medical Implant Communications Service (MICS) standard in the 402–405MHz band. The transmitter meets MICS mask specifications with data rates up to 1...

OOK Super-Regenerative Receiver for Medical Implant Communications

Recent advances in the medical field are spurring the need for ultra-low power transceivers for wireless communication with medical implants. To deal with the growing demand for medical telemetry, the FCC commissioned the Medical Implant Communications Services (MICS) standard in 1999 in the 402–405 MHz band. This paper presents a 350 W FSK/MSK direct modulation transmitter and a 400 W OOK supe...

315MHz OOK transceiver with 38-µW receiver and 36-µW transmitter in 40-nm CMOS

A Low-Power 2.4-GHz Transmitter/Receiver CMOS IC

A 2.4-GHz CMOS receiver/transmitter incorporates circuit stacking and noninvasive baseband filtering to achieve a high sensitivity with low power dissipation. Using a single 1.6-GHz local oscillator, the transceiver employs two upconversion and downconversion stages while providing on-chip image rejection filtering. Realized in a 0.25m digital CMOS technology, the receiver exhibits a noise figu...

A 2.4-GHz 22-Mbps CMOS OOK transmitter for wireless body area network

A 2.4-GHz CMOS on-off keying (OOK) transmitter is developed for applications that require high data rate over 10Mbps in the area of wireless body area network (WBAN) and medical implant communication service (MICS). A novel analog pulse-shaping circuit for reducing power consumption and circuit complexity is employed for the OOK transmitter. Fabricated in 0.13μm CMOS, the transmitter core exclu...
