Abstract :
Current-reuse and gate-modulation techniques have been presented for ultra-low power and low phase noise quadrature voltage-controlled oscillator (QVCO) design. The proposed topology overcomes the trade-off between low phase noise and low power consumption. Results demonstrate a phase noise of -123.7-dBc/Hz at 1-MHz offset while consuming only 680-uW (including output buffers) with a 1.1-V supply.
