%X a new nullor-based model to describe the behavior of operational transresistance amplifiers (otras) is introduced. the new model is composed of four nullors and three grounded resistors. as a consequence, standard nodal analysis can be applied to compute fully-symbolic small-signal characteristics of otra-based analog circuits, and the nullor-based otras model can be used in cad tools. in this manner, the fully-symbolic transfer functions of several application circuits, such as filters and oscillators can easily be approximated.
