Fabio Padovan1, Fabio Quadrelli1,2, Matteo Bassi1, Marc Tiebout1, Andrea Bevilacqua2 Infineon Technologies, Villach, Austria University of Padova, Padova, Italy 1 2 The relentless development of next-generation communication and radar systems sets increasingly stringent requirements on the spectral purity of local oscillators. Decreasing phase noise is crucial to support efficient modulation formats with large symbol constellations, as well as to enable innovative radar applications, e.g., anti-collision, gesture recognition, and medical imaging. To minimize phase noise, bipolar transistors offer some advantages over ultra-scaled CMOS: higher supply voltage (thus larger oscillation amplitudes), lower 1/f noise, higher-Q passives (due to higher resistivity substrate and, possibly, thicker metals), and higher fT, fmax for a given technology node, which results in a cost advantage for a variety of medium-volume applications (e.g., infrastructure transceivers).
