Abstract
An asymmetrical wireless interface and transceiver designed for implanted medical image applications are reported. The proposed system operated at the 402–405 MHz MICS (Medical Implantable Communication System) band, and it utilizes different modulation schemes for uplink and downlink to lower power consumption and reduce circuit implementation complexity. A high data rate (524 kbps within 300-kHz channel and maximum 1.5 Mbps) and low-power (12.7 mW) direct-modulation FSK transmitter is proposed for medical image transmission, and a low-power (3.3 mW) superregenerative OOK receiver is adopted for command receiving. The wireless interface design considerations and key circuit realizations are presented in this paper.
