ABSTRACT:
Circuit blocks for integrating/differentiating input signals in the form of sampled currents include coupled current memories where the second current memory has a plurality of scaled outputs which feed switching arrangements. Resistors are provided in the current memories, the resistance of the resistors being equal to the "on" resistance of the switching arrangement multiplied by any multiplying factor applied to this output to which the switching arrangement is coupled.
