Analysis of Limit Cycles in a PI Digitally Controlled Buck Converter

Bradley, Mark ; Alarcon, E. ; Feely, Orla (IEEE, 2012-05-20)

Digital control of power converters has been an area of considerable research interest in recent times. One of the problems which arises in these systems is that of the limit cycle oscillations that occur due to quantization ...
A kicked oscillator as a model of a pulsed MEMS system

Blokhina, Elena ; Feely, Orla (World Scientific Publishing, 2009-01)

In this paper, we study the behaviour of a MEMS oscillator by applying methods of nonlinear dynamics. We model the system as a kicked damped oscillator and obtain the iterative maps that describe the MEMS system. The ...
Limit Cycle Behavior in a Class-AB Second-Order Square Root Domain Filter

De La Cruz Blas, Carlos A. ; Feely, Orla (Springer, 2011-08)

This paper shows how an unwanted limit cycle can be exhibited by a second-order CMOS companding filter. The filter employs the quasi-quadratic law of the MOS transistor in strong inversion and saturation to achieve compression ...
Limit cycles in a digitally controlled buck converter

Bradley, Mark ; Feely, Orla ; Teplinsky, Alexey (IEEE, 2011-08-29)

We describe the mathematical model of a digitally controlled buck converter. This model is an autonomous discrete-time discontinuous piecewise-linear dynamical system in three dimensions. Investigating this system, we ...
