A Compact RF CMOS Amplifier LC Output Matching Circuit
提出了一种紧凑的射频互补金属氧化物半导体(Complementary Metal Oxide Semiconductor,CMOS)放大器LC输出匹配电路,利用放大器漏极偏置电感、输出端隔直电容与放大器输出端并联电感电容形成高阶LC谐振网络,可在占用较小芯片面积的条件下实现较传统L型匹配电路更宽频率范围的输出阻抗匹配.推导了该LC输出匹配电路元件值的计算式,并根据提出的设计方法,采用 65 nm CMOS工艺设计了一款K频段放大器,其输出匹配电路…查看全部>>
A compact radio frequency(RF)complementary metal oxide semiconductor(CMOS)amplifier LC output matching circuit is proposed.A high-order LC resonant network is formed by using the drain bias inductor,the output DC block capacitor,and the output parallel LC of the amplifier.It can achieve output impedance matching in a wider frequency range than traditional L-type matching circuit under the condition of occupying a small chip area.The formula for calculating t…查看全部>>
