报道了一种采用自共源共栅结构和体端耦合的低压低功耗注入锁定射频振荡器。自共源共栅结构促进每个导电路径中的更高电阻，并且帮助实现低功率操作而不降低电压净空。体端子耦合提供注入锁定，而不会明显增加功耗。该振荡器采用0.18 μ m RF CMOS工艺制造，工作电压低至0.9 V，工作频率为1.30 GHz时功耗仅为1.161 mW。 相对较低的功耗使该设计非常适合低功耗发射机应用。
A low-voltage low-power injection-locked RF oscillator using a self-cascode structure and body terminal coupling is reported. A self-cascode structure facilitates higher resistance in each conducting path and helps achieve low-power operation without degrading the voltage headroom. Body terminal coupling provides injection-locking without appreciably increasing the power consumption. The proposed oscillator fabricated in 0.18 µm RF CMOS process can operate with a supply voltage as low as 0.9 V and consumes only 1.161 mW of power for 1.30 GHz operating frequency. Relatively low power consumption makes the design highly suitable for low-power transmitter applications.
