介绍了一种基于0.18 μm CMOS工艺的无电池ASK/O-QPSK发射机。432 MHz发射器使用相同的54 MHz信号源进行注入锁定频率合成和RF供电，以实现无电池工作。发射机的输出功率为-15.1 dBm。相位噪声分别为-112.6和-116.1 dBc/Hz，在432 MHz的100和1 MHz的偏移。ASK和O-QPSK调制方案的最大数据速率分别为50 kbit/s和2.5 Mbit/s。
A battery-less ASK/O-QPSK transmitter is presented using 0.18 μm CMOS technology for medical implants. The 432 MHz transmitter uses an identical signal source of 54 MHz for injection-locked frequency synthesis and RF powering to accomplish battery-less operation. The transmitter exhibits an output power of -15.1 dBm. The phase noises of -112.6 and -116.1 dBc/Hz are achieved at offsets of 100 and 1 MHz from 432 MHz, respectively. The maximum data rates are 50 kbit/s and 2.5 Mbit/s for ASK and O-QPSK modulation schemes, respectively.
