“…In the literature, various RF circuit blocks adopting the current-reuse technique can be found [3,4,5]. For example, stacked VCO and divider [3], stacked LNA, mixer and VCO [4], and stacked VCO and power amplifier [5] can be effective for improving the current dissipation, particularly, in the carrier generation block, receiver block, and transmitter block, respectively, in RF transceivers.…”

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 0.18 µm CMOS, the transmitter dissipates 9.3 mW from a 1.8-V supply. Measurement shows that the gain boosting capability increases the output power by 1.3-5.5 dB, 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.
