【摘要】：提出了一種基于柵極電感反饋的Vacker壓控振蕩器(VCO),該結(jié)構(gòu)能夠改善電路的負(fù)阻抗,進(jìn)而使得電路易于起振。對(duì)晶體管的負(fù)載效應(yīng)和振幅穩(wěn)定性的分析表明,該Vacker VCO相比較于Colpitts VCO,具有更好的振幅穩(wěn)定性,進(jìn)而改善了VCO的相位噪聲�；�0.13μm RF CMOS工藝,對(duì)該Vacker VCO進(jìn)行了設(shè)計(jì)與芯片實(shí)現(xiàn),測(cè)試結(jié)果表明:在消耗4.2 mW功耗的前提下,該VCO振蕩頻率為11 GHz～12.6 GHz,在11.8 GHz振蕩頻率處,相位噪聲為-115.1 dBc/Hz@1 MHz,品質(zhì)因數(shù)FOM指標(biāo)達(dá)到-190.3 dBc/Hz。
[Abstract]:A novel VCO based on gate inductance feedback is proposed, which can improve the negative impedance of the VCO and make the VCO oscillate easily. The analysis of the load effect and amplitude stability of the VCO shows that the VCO has better amplitude stability than the Colpitts VCO, and thus improves the phase of the VCO. Noise. Based on the 0.13 micron RF CMOS process, the Vacker VCO is designed and implemented on the chip. The test results show that the oscillation frequency of the VCO is 11 GHz to 12.6 GHz, the phase noise is -115.1 dBc/Hz@1 MHz at 11.8 GHz oscillation frequency, and the quality factor FOM index reaches - 190.3 dBc/Hz.
