| 中文摘要 | A low power high data rate wireless endoscopy transceiver is presented. Transceiver architecture.. circuit topologies and design trade-offs have been considered carefully to satisfy the tight requirements of the medical endoscopy capsule: lower power consumption, high integration degree and high data rate. The prototype, implemented in 0.25 mu m CMOS, integrates a super-heterodyne receiver and a super-heterodyne transmitter on a single chip together with an integrated RF local oscillator and LO buffers. The digital modulation and demodulation is also implemented in analog field and no data converters are needed for the whole endoscopy capsule. The measured sensitivity of the receiver is about -70 dBm with a data rate 256 kbps, and the measured output power of the transmitter could achieve -23 dBm with a data rate 1 Mbps. The transceiver operates from a power supply of 2.5 V, while only consuming 15 mW in receiver (RX) mode and 14 mW in transmitter (TX) mode. (c) 2007 Elsevier Ltd. All rights reserved. |
