An original multifunctional structure with improved performances will be presented. The great advantages of increased modularity, controllability and of the associated reduced design costs represent an immediate consequence of multiple functions that could be implemented by the proposed structure: amplifying, multiplying, squaring or simulating positive and negative resistances. The circuit accuracy...
A new current-mode function generator circuit will be presented, having a much smaller complexity per function with respect to the previous reported similar works. The circuit allows to compute an important number of mathematical functions using their n-th order limited polynomial series expansion. The approximation error could be strongly decreased by increasing the number of terms considered in...
The main advantages of the new proposed CMOS active resistor are the improved linearity, the small area consumption and the improved frequency response. An original technique for linearizing the I(V) characteristic of the active resistor is proposed, based on the utilization of a new linear differential amplifier and on a current-pass circuit. The linearization of the original differential structure...
A new n inputs current-mode Euclidean distance circuit will be presented. For improving the-circuit frequency response, only MOS transistors working in saturation will be used and a current-mode operation of the circuit will be imposed. The circuit output current, which represents the Euclidean distance function, is not dependent on technological parameters, with the result of an important reducing...
