摘要：

In this letter, a constantly low-phase-noise voltage-controlled oscillator (VCO) with wide frequency tuning range (FTR) (44.4%) is presented. The presented VCO is based on a four-pole tunable bandpass filter (BPF) with quasi-elliptic frequency response and constant absolute bandwidth (CABW). Because the four-pole quasi-elliptic BPF is used, the low phase noise of the VCO is obtained, and because the CABW of the filter is kept within a wide FTR, the low phase noise is maintained over the wide FTR. Based on this concept, a demonstrative VCO is designed and measured. The oscillation frequency of the demonstrative VCO is able to be tuned from 1.35 to 2.12 GHz (44.4%) and the phase noise keeps better than -101.3 dBc/Hz at 100 kHz and -127.8 dBc/Hz at 1 MHz over the FTR.
