International Journal for Numerical Methods in Engineering, 2008 AbstractNowadays, most of the ordinary differential equations (ODEs) can be solved by modelica‐based approaches, such as Matlab/Simulink, Dymola and LabView, which use simulation technique (ST). However, these kinds of approaches restrict the users in the enforcement of conditions at any instant of the time domain.

Quadrature Mismatch Shaping Techniques for Fully Differential Circuits [PDF]
2007 IEEE International Symposium on Circuits and Systems (ISCAS), 2007 Quadrature SigmaDelta ADCs require a feedback path for both the I and the Q part of the complex feedback signal. A complex DAC could give this feedback with near-perfect I/Q balance. Still, the mismatch between the unit elements of the complex DAC introduces mismatch noise that should be shaped out of the signal band with dynamic element-matching (DEM)
