79GHz Push-Push Oscillators in 0.13µm SiGe BiCMOS Technology
Résumé
This paper describes VCO designs based on varactor tuned Push-Push architecture. Two versions (powered under 1.2V and 1.8V) of the 79GHz oscillators have been designed in a 0.13µm SiGe BiCMOS technology, thus targeting automotive Radar and millimeter-wave applications. Their tuning ranges are respectively set on 6GHz (7.6%) and 7GHz (8.8%). The oscillator cores solely consume 18mW and 30mW, and both achieve low phase noise characteristics -102dBc/Hz at 1MHz offset from the carrier frequency (80GHz) and output powers of 18dBm and 0dBm respectively.
