Resumen: In this work a CMOS 1.2V 5GHz low-power voltage-controlled oscillator (VCO) is proposed. It uses an on-chip biased LC-tank topology and introduces a temperature compensation technique which stabilizes the oscillation amplitude for a robust I/Q generation using a frequency divider-by-2. Compared to a standard design with constant bias, it reduces the oscillation variation by almost two orders of magnitude between 0°C and 100°C with negligible impact on the phase noise. Worst case estimations of the VCO phase noise after layout parasitic extraction are -110.1dBc/Hz and -126.6dBc/Hz at 1MHz and 5MHz offsets from the carrier, respectively. Its nominal current consumption is 198μA (plus 22.5μA for biasing) and it occupies 370×530μm2.
