| dc.description.abstract | The content of this thesis is about microwave oscillator integrated circuit design.
The push-push oscillator topology is used in this thesis to lower phase noise of high
oscillation frequency oscillator. General phase noise theory on push-push oscillator is
developed to prove it’s naturally having low phase noise property. WINTM pHEMT
0.15-μm technology is adopted to implement：(1) Ka-band fundamental VCO. The
oscillation frequency is 24.97 GHz, tuning range is 270 MHz, and phase noise is
-96.84 dBc/Hz at 1MHz offset；(2) The second circuit is a Ku-band Finite Ground (FG)
CPW fundamental oscillator. The oscillation frequency is 14.75 GHz, phase noise is
-118.96 dBc/Hz at 1 MHz offset, and -191.8 dBc/Hz of Figure-of-Merit(FOM)；(3)
The third circuit is a Ka-band FG CPW push-push oscillator. The oscillation
frequency is 30.3 GHz, phase noise is -113.2 dBc/Hz at 1MHz offset, and FOM is
-188.16 dBc/Hz. Finally, TSMC CMOS 0.18-μm technology is adopted to implement
the fourth circuit which is a Ka-band cross-coupled push-push VCO. The oscillation
frequency is 26.7 GHz, tuning range is 1.95 GHz, phase noise is -117.5 dBc/Hz at
1MHz offset and exhibited an excellent FOM of -199.82 dBc/Hz. | en_US |
