A new differential delay cell with complementary current control to extend the control voltage range as well as the operation frequency is proposed for low voltage and wide tuning range voltage-controlled ring oscillator (VCRO). The complementary current control can get rid of the restriction that control voltage is unable to cover the full range of power supply voltage in a conventional VCRO. A three-stage VCRO chip working with 1 V power supply voltage is constructed using 0.18 μm 1P6M CMOS process for verifying the efficacy of the proposed differential delay cell. Measured results of the VCRO chip show that a wide range of operation frequency from 4.09 GHz to 479 MHz, a tuning range of 88%, is achieved for the full range of control voltage from 0 to 1 V. The power consumptions of the chip are 13 and 4 mW for oscillation outputs of 4.09 GHz and 479 MHz, respectively. The measured phase noise is ―93.3 dBc/Hz at 1 MHz offset from 4.09 GHz center frequency. The core area of the chip is 106 μm x 76.2 μm.
