Abstract

A quadrature voltage-controlled oscillator (QVCO) utilizing the enhanced wideband-harmonic-shaping technique to improve phase noise (PN) and reduce the 1/ ${f} ^{3}$ PN corner is presented. Specifically, our QVCO uses triple-coil magnetic coupling for quadrature phase generation, additionally boosts the common-mode (CM) impedance and harmonic voltage, and contributes to a well-defined CM current returning path for PN improvement and flicker noise upconversion reduction. Besides, the head resonator (HR) enables wideband-harmonic-shaping operation and facilitates without manual second harmonic alignment. The QVCO is implemented in 55-nm CMOS and occupies a core area of 0.362 mm2. The measured peak PN is −124.2 dBc/Hz at 1-MHz offset, and the estimated 1/ ${f} ^{3}$ PN corner varies from 63 to 89 kHz across the entire operating range of 17% (4.14–4.97 GHz).

使用增强型宽带谐波整形技术的 63-89 kHz 1/f³ 相位噪声角 QVCO
本文介绍了一种正交压控振荡器(QVCO),该振荡器利用增强型宽带谐波整形技术来改善相位噪声(PN)并降低 1/{f}$ PN 角。^{3}$ PN 角。具体来说,我们的 QVCO 采用三线圈磁耦合来产生正交相位,此外还增强了共模(CM)阻抗和谐波电压,并有助于形成明确的 CM 电流返回路径,从而改善 PN 并降低闪烁噪声上变频。此外,头部谐振器(HR)可实现宽带谐波整形操作,无需手动进行二次谐波校准。QVCO 采用 55 纳米 CMOS 实现,核心面积为 0.362 平方毫米。在 1-MHz 偏移时,测得的峰值 PN 为 -124.2 dBc/Hz,估计的 1/ ${f}^{3}$ PN 为 -124.2 dBc/Hz。^{3}$ PN 角在整个 17% 工作范围(4.14-4.97 GHz)内的变化范围为 63 至 89 kHz。
