Analog electronic cell, in particular for be implantee in a circuit integrated, and circuit integrated comprising such cells

摘要

This elementary unidirectional analog electronic cell, in particular to be implanted in a programmable analog integrated circuit, and comprising an input terminal (E), an output terminal (S), characterised in that it comprises: a current conveying structure with two inputs (X, Y) and one output (Z), one of the inputs (Y) being connected to the input terminal (E) of the cell, the output (Z) being connected to the output terminal (S) of the cell; two parallel RC circuits (R1, C1; R2, C2) each connected to a reference potential (M1, M2) respectively and to the free input (X) of the current conveyor, and to the output terminal (S) of the cell receptively, the values of the resistors and the capacitors (R1, C1; R2, C2) being electronically adjustable to predetermined values for providing to the cell a transfer function of order 0 or 1.
