Abstract

This paper presents a quadrature VCO (QVCO) that employs gate-to-drain transformers to couple two fundamental oscillators to generate accurate quadrature phases and switched coupled inductors for tuning extension. Thanks to these techniques, it is possible to cover two bands with a single quadrature VCO, without jeopardizing phase noise or demanding extensive silicon area. The oscillator, realized in 28nm HPM bulk CMOS, occupies a core area of only 0.031mm2 and is tunable from 71-to-76GHz and 85.6-to-90.7GHz, resulting in a total tuning range of 9.8GHz. The peak phase noise at 10MHz offset from the carrier is - 117.7dBc/Hz in the lower band and -110dBc/Hz in the higher one and varies less than 3.5dB within each sub-band. The maximum phase error is 1.5° and 3.5° in the lower and higher band respectively.
一种带开关耦合变压器的双频e波段正交压控振荡器
本文提出了一种正交压控振荡器(QVCO),它利用栅极-漏极变压器耦合两个基振产生精确的正交相位,并利用开关耦合电感进行调谐扩展。由于这些技术,可以用单个正交压控振荡器覆盖两个频段,而不会损害相位噪声或需要广泛的硅面积。该振荡器采用28nm HPM块体CMOS实现,核心面积仅为0.031mm2,可在71- 76ghz和85.6- 90.7 ghz范围内调谐,总调谐范围为9.8GHz。在载波偏移10MHz处,峰值相位噪声在低频段为- 117.7dBc/Hz,在高频段为- 110dbc /Hz,在每个子频段内变化小于3.5dB。下波段和上波段的最大相位误差分别为1.5°和3.5°。
