Abstract :
This paper presents a graphical approach for the application of a compact current based MOS model, valid in all regimes of operation, in the design of CMOS operational transconductance amplifiers. Since a large amount of information is made available in the form of contour plots, the method provides a deep insight of design feasibility and allows a rapid and reliable determination of transistor dimensions that satisfy design specifications and saturation conditions. The adjustable contour plots are generated by a sizing program implemented in MATLAB.
