Abstract :
A compact and fully programmable Gaussian function circuit with temperature compensation is introduced. The programmability of the Gaussian circuit generator is carried out by using current sources. Hspice simulations for the proposed structure have shown deviations from the ideal Gaussian function below 3%. Breadboard results for the Gaussian circuit generator, in good agreement with the theoretical ones, are reported
