A 92-GHz deterministic quadrature oscillator and N-push modulator in 120-nm SiGe BiCMOS

Abstract

A voltage-controlled traveling wave oscillator is proposed for deterministic quadrature phase generation. This oscillator topology contains four traveling-wave gain stages that provide 360o phase shift around transmission line ring. The oscillator has a center frequency of 92 GHz and a tuning range of 1.3 GHz. The constructive-wave oscillator is fabricated in a 120-nm SiGe BiCMOS process and occupies a total area of 0.65 × 0.67 mm2 with a power consumption of 32mW.
