摘要

介绍了一种高性能、低功耗的2.4 GHz生物医学射频发射机。该设计采用LC电压控制振荡器(VCO)、ASK调制器和逆D类(D−1)功率放大器(PA)。ASK对低相位噪声LC-VCO产生的载波信号进行调制，然后将调制后的信号通过逆d - 1类PA进行放大。该射频发射机的输出功率为- 11.14 dbm，效率为3.88%。它还支持130 mb /s的数据速率，功耗为1.98 mw。该设计采用0.13μm CMOS工艺技术，并完全集成在片上。

Low-power and high-performance 2.4 GHz RF transmitter for biomedical application

A high performance and low power 2.4 GHz radio frequency (RF) transmitter for biomedical application is presented. The design utilizes LC voltage control oscillator (VCO), ASK modulator, and an inverse Class-D (D−1) power amplifier (PA). The ASK modulates the carrier signal generated by a low phase noise LC-VCO, then the modulated signal is amplified by the inverse Class-D−1 PA. The proposed RF transmitter achieves −11.14-dBm output power with 3.88% efficiency. It also supports 130-Mb/s data rate and consumes 1.98-mW. The design has been implemented in a 0.13μm CMOS process technology and fully integrated on-chip.
