本文提出了一种适用于宽调谐范围、高速的压控环形振荡器的CMOS差分延迟单元。采用互补电流控制方案的差分延迟单元不仅可以提高控制电压范围，还可以提高低压工作时的工作频率。使用新的延迟单元，采用三级结构和多通环路技术的环形压控振荡器在1.8 V电源电压下，在0.18µm单聚六金属（1P6M） CMOS工艺中实现，以实现宽调谐范围和高速。测量结果表明，在0 ~ 1.8 V全范围控制电压下，工作频率范围为8.36 ~ 1.29 GHz。当电源电压为1v时，工作频率为4.09 ~ 0.479 GHz，全量程控制电压为0 ~ 1v。在与8.35 GHz中心频率偏移1 MHz时，测量到的相位噪声为-100.22 dBc/Hz，性能因数（FOM）为-159.95 dBc/Hz。无PAD的芯片核心面积为106×76.2µm2。
A new complementary metal oxide semiconductor (CMOS) differential delay cell for a voltage-controlled ring oscillator with a wide tuning range and high speed is proposed in this paper. The new differential delay cell employing a complementary current control scheme can increase not only the control voltage range but also the operation frequency in low-voltage operation. Using the new delay cells, a ring voltage-controlled oscillator employing a three-stage structure and multiple-pass loop techniques is implemented in the 0.18 µm single-poly–six-metal (1P6M) CMOS process at a 1.8 V supply voltage to achieve a wide tuning range and high speed. Measured results show that a wide operation frequency range from 8.36 to 1.29 GHz is accomplished for the full-range control voltages from 0 to 1.8 V. When the supply voltage is 1 V, the operation frequencies are from 4.09 to 0.479 GHz for the full-range control voltages from 0 to 1 V. The measured phase noise is -100.22 dBc/Hz at 1 MHz offset from the 8.35 GHz center frequency and the figure of merit (FOM) is -159.95 dBc/Hz. The chip core area without PAD is 106×76.2 µm2.
