In this paper, we propose a quadrature oscillator-mixer combination. This circuit reuses the bleeding current, which relaxes mixer design trade-offs noise, linearity and gain at low supply voltages, by replacing the bleed current source as an oscillator. The linearized merged oscillator-mixer achieves a 8 dB gain, −4 dBV IIP3 and 6.5 dB white noise figure at the 7 GHz frequency. The phase-noise of the quadrature oscillator is −97 dBc/Hz at the 1 MHz offset from the 7Ghz LO frequency. The circuit consumes 10 mA from a 1.2 V supply.
