摘要：

A tunable second-order lowpass filter architecture capable of operating in the gigahertz frequency range is proposed. Two Q-enhancement techniques are utilized to extend the Q tuning range. Simulation results employing standard 0.5 mu m CMOS technology have successfully verified that the center frequency tuning and the hybrid Q-tuning approach operate between 1.26GHz and 2.3GHz center frequencies with Q larger than 1000. A tunable lowpass filter with a center frequency at 2.07GHz with a Q equal to 31 is designed to have e 44dB input dynamic range and 27.8mW power dissipation.
