A 10 GHz quadrature voltage controlled oscillator (QVCO) is implemented using a transformer-coupled resonator. The VCO can be tuned between 10.2 and 11.4 GHz and has low phase noise of -118.67 dBc/Hz at 1 MHz offset frequency with 1.8 V power supply. The figure of merit (FOM) is 188 dB. The 20 GHz differential signal is generated by harmonics of quadrature signals of the VCO with a balanced frequency doubler. To increase the output power of the harmonics, pinch-off clipping is used without any buffers or DC level shifter, since the proposed VCO has RF signals with low DC level. The frequency multiplier, the output of which can be tuned between 19.8 and 22 GHz, has a low noise of - 111.67 dBc/Hz at 1 MHz offset frequency. The phase noise of the multiplier is 7 dB higher than that of the VCO.

This work describes the first use of native EPROM devices (available in every standard CMOS technology) and switched reactances to relax these tradeoffs. In addition to permitting post-packaging compensation for manufacturing variations, the inherent reprogrammability of these cells also enables the rapid prototyping and optional reconfiguration of RF and mixed-signal systems. This technology allows the realization of a fully-integrated oscillator in 0.25 μm CMOS with a phase noise variation of under 10 dB (compared with 40 dB variation in a conventional implementation) over a 1.25 GHz to 1.92 GHz (42%) tuning range. The oscillator consumes 23 mW from a 3 V supply while exhibiting a phase noise of better than -93dBc/Hz at 100 kHz offset from a nominal 1.58 GHz center frequency.","PeriodicalId":140604,"journal":{"name":"2004 IEE Radio Frequency Integrated Circuits (RFIC) Systems.
