Abstract
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 the component values of the LC output matching circuit is deduced,and according to the proposed design method,a K-band amplifier is designed with a 65 nm CMOS process,and its output matching circuit size is only 98 μm×150 μm.The simulation results show that S22 of the amplifier is less than-10 dB in 16.5～22.1 GHz,and the impedance matching bandwidth is increased by 166%compared with that of the L-type matching circuit.The measured S-parameters of the amplifier are consistent with the simulation ones,which verifies that the LC matching circuit can achieve compact broadband impedance matching.关键词
