Phase noise can vary dramatically over the tying range of a VCO, but the published literature often obscures this fad by reporting phase noise measurements at only a small number of selected turning voltages. It is diffcult to obtain simultaneously a large tuning range, low phase noise, and small phase noise variation, particularly while accommodating manufacturing and packaging tolerances. 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 they 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 0.25μm CMOS with a phase noise variation of under lOdB (compared with 40dB variation in a conventional implementation) over a 1.25GHz to 1.92GHz (42%) tuning range. The oscillator consumes 23mW from a 3V supply while exhibiting a phase noise of better than -93dBdHz at 100kHz offset from a nominal 1.58GHz center frequency.
