Claim 1
Independent Claim
198 words
A CIRCUIT FOR SQUARING AN INPUT SIGNAL COMPRISING FIRST AND SECOND SEMICONDUCTOR DIODES CONNECTED IN SERIES TO FORM A COMMON JUNCTION, SAID DIODES BEING POLED TO PERMIT RESPECTIVE CURRENT FLOWS THERETHROUGH IN OPPOSITE DIRECTIONS WITH RESPECT TO SAID COMMON JUNCTION, A TRANSISTOR HAVING A BASE, COLLECTOR AND EMITTER, THE SAID COLLECTOR BEING CONNECTED TO THE SAID COMMON JUNCTION AND SAID BASE AND EMITTER BEING CONNECTED TO RESPECTIVE FIRST AND SECOND FIXED ELECTRICAL POTENTIAL SOURCES, A FIRST CAPACITOR CONNECTED TO THE FACE OF SAID FIRST DIODE OPPOSITE THE SAID COMMON JUNCTION, FIRST AND SECOND RESISTORS HAVING SUBSTANTIALLY EQUAL RESISTANCES, A THIRD FIXED ELECTRICAL POTENTIAL SOURCE, SAID FIRST RESISTOR BEING CONNECTED BETWEEN (1) THE JUNCTION OF SAID CAPACITOR AND SAID FIRST DIODE, AND (2) THE SAID THIRD POTENTIAL SOURCE, SAID SECOND RESISTOR BEING CONNECTED BETWEEN (1) THE FACE OF THE SAID SECOND DIODE OPPOSITE THE SAID COMMON JUNCTION, AND (2) THE SAID THIRD POTENTIAL SOURCE, A SECOND CAPACITOR, ONE SIDE OF SAID SECOND CAPACITOR BEING CONNECTED TO THE FACE OF THE SAID SECOND DIODE OPPOSITE THE SAID COMMON JUNCTION, AND A CONSTANT IMPEDANCE LOAD CONNECTED BETWEEN (1) A REFERENCE POTENTIAL SOURCE, AND (2) THE OTHER SIDE OF SAID SECOND CAPACITOR.
