complementary push-pull and differential push-push
oscillators. Colpitts is very well suited modern, highspeed CMOS technologies as the capacitors can be implemented in the top metal layers, which can be used
to create precise capacitors. For high quality oscillator design, Colpitts can easily be combined with MEMS
high Q resonators such as FBAR, SAW and BAW placed
outside a CMOS chip.
Acknowledgment

Mehdi Azadmehr received his master
and Ph.D. degree in Nanoelectronics
from the University of Oslo, Norway, in
2009. His Ph.D. work aimed at designing
bi-directional circuit for use as interface for resonating sensors. He then
worked as assistant professor in 2 years at Vestfold University College and is now employed as associate professor at University of South-Eastern Norway. He spent one
year at University of Illinois at Chicago where he conducted research on oscillator circuits as front-end for
PM sensors. Main research areas are low power analog
electronic design with focus on interface circuits.
Igor Paprotny (Member, IEEE) received
the Ph.D. degree in computer science
from the Dartmouth College, Hanover,
NH, USA. He is currently an Associate
Professor with the Department of Electrical and Computer Engineering, University of Illinois at Chicago, Chicago, IL, USA. He is also
the Consortium Lead for the Air-Microfluidics Group
(AMFG). He has authored five book chapters, over 50 articles in journals and conference, and holds four patents.
His research interests include microrobotics, energy
systems sensing, and air-microfluidics.
Luca Marchetti received B.S. degree in
electronics engineering from Universita' Politecnica delle Marche, Ancona, Italy in 2012, the M.S. degree in Power
electronics from Polytechnic University
of Turin, Torino, Italy in 2015. He concluded is Ph.D in Micro and Nano systems at University
College of South-Eastern Norway, where he is currently
working as postdoctoral researcher. His research and
