摘要

为了实现无线通信中的压控振荡器(VCO)，研制了一种采用新型可调谐环形滤波器的器件。该振荡器是基于可调环形滤波器，具有紧凑和锐利的抑制滤波器，高性能有源电感。它工作在3.2 GHz到4.1 GHz的频率范围内。在3.5GHz载波100kHz偏移时，VCO的相位噪声电平为-93dBc/Hz。

Design and analysis of VCO with tunable ring filter

To realize a voltage controlled oscillator (VCO) in wireless communications, a device is developed using a new tunable ring filter. The oscillator is based upon the tunable ring filter, with a compact and sharp rejection filter, high performance active inductor. It operates in the 3.2 GHz to 4.1 GHz frequency range. The VCO's phase noise level is -93dBc/Hz at 100kHz offset from a 3.5GHz carrier.
