This talk provides an overview of noise analysis techniques and noise models for radio frequency (RF) circuits and the implication of noise constraints on RF circuit design. In order to accurately account for the circuit nonlinearities, the circuit noise sources are modelled as stochastic processes and the circuit equations are solved with these stochastic processes as inputs, using techniques from stochastic calculus. Noise analysis and modelling techniques are presented for both autonomous (oscillatory) and non-autonomous circuits. Using these models, noise analysis of a phase feedback system (phase-locked loop) is also presented.


Amit Mehrotra received B. Tech. degree in Electrical Engineering from Indian Institute of Technology, Kanpur in 1994 and Masters and PhD from Department of Electical Engineering and Computer Science, University of California at Berkeley in 1996 and 1999 respectively. In August 1999 he joined the University of Illinois at Urbana-Champaign where he is currently an Assistant Professor with the Department of Electical and Computer Engineering and a Research Assistant Professor with the Illinois Center for Integrated Micro-Systems group at the Coordinated Science Laboratory. He is a member of the IEEE .
