Fully Programmable CMOS traingular and trapezoidal function generators

A Triangular and trapezoidal transconductor circuits with a Programmable slope (keeping constant height or constant width and making the other variable) and also horizontal position are presented. Triangular and trapezoidal function generators have many applications like high speed folding analog-to-digital convertors, a piecewise-linear approximation and also used in fuzzy controller. PSPICE simulation confirms the analytical analysis of the proposed circuits using 0.25µm technology is also given.
