A current-reuse MICS band CMOS RF transmitter for implantable cardioverter telemetry system

[摘要] References(5)Cited-By(1)A MICS band CMOS RF transmitter is presented for implantable cardioverter telemtry system. Current-reuse and gain boosting techniques are employed for reducing the current consumption as well as improving the output power. Fabricated in 0.18µm CMOS, the transmitter dissipates 9.3mW from a 1.8-V supply. Measurement shows that the gain boosting capability increases the output power by 1.3-5.5dB, while the image and LO suppression is unaffected. The proposed approach can be effective for a low-power RF transmitter design in implantable telemetry devices.
