All-pass and low-pass filter comprised of active element circulators
Abstract
Abstract THIS SPECIFICATION DISCLOSES THE USE OF A CIRCULATOR HAVING AT LEAST THREE PORTS FOR THE SIMULATION OF NETWORKS WHICH IN THEIR NORMAL REALISATIONS INCLUDE ONE OR MORE INDICUTIVE ELEMENTS. VARIOUS CIRCUIT ARRANGEMENTS ARE DESCRIBED INCLUDING ONE OR MORE CAPACITORS CONNECTED IN RESPECTIVE PATHS BETWEEN DIFFERENT PAIRS OF PORTS OF THE CIRCULATOR AND POSSIBLY ALSO INCLUDING ONE OR MORE CAPACITORS CONNECTED FROM PORTS OF THE CIRCULATOR TO GROUND, INPUT AND OUTPUT PORTS OF THE CIRCUITS BEING CONNECTED TO PORTS OF THE CIRCULATOR. DEPENDING ON THE DIFFERENT CONNECTIONS OF THE CAPACITORS OF THE CIRCULATOR LOW-PASS AND ALL-PASS FILTERS OF VARIOUS ORDERS CAN BE PRODUCED. THE USE OF THE INVENTION HAS THE ADVANTAGE THAT THE FILTERS CAN BE PRODUCED WITHOUT THE INCORPORATION OF PHYSICAL INDUCTORS WHICH IS OF IMPORTANCE IN THE REALISATION OF THE FILTERS IN MICRO-CIRCUIT FORM.
