Claim 1
Independent Claim
180 words
A REGENERATIVE FREQUENCY DIVIDER CIRCUIT COMPRISING: A NARROW JUNCTION DEGENERATE SEMICONDUCTOR DIODE DEVICE EXHIBITING A NEGATIVE RESISTANCE REGION IN THE LOW FORWARD VOLTAGE RANGE OF ITS CURRENT-VOLTAGE CHARACTERISTIC; BIAS MEANS IN CIRCUIT WITH SAID DIODE DEVICE ESTABLISHING AN AVERAGE DIRECT CURRENT OPERATING POINT THEREFOR IN SAID NEGATIVE RESISTANCE REGION; AND INDUCTANCE CONNECTED IN SERIES CIRCUIT BETWEEN SAID DIODE DEVICE AND SAID BIAS MEANS, SAID INDUCTANCE ACTING IN OPPOSITION TO ANY CURRENT CHANGE IN SAID DIODE DEVICE WHEREBY SAID DIODE DEVICE IS CAUSED TO SWITCH FROM A LOWER VOLTAGE OPERATING CONDITION TO A HIGHER VOLTAGE OPERATING CONDITION AND FROM A HIGHER VOLTAGE OPERATING CONDITION TO A LOWER VOLTAGE OPERATING CONDITION WITH A REPETITION RATE SUBSTANTIALLY DETERMINED BY SAID INDUCTANCE AND THE EFFECTIVE RESISTANCE IN SERIES WITH SAID DIODE DEVICE THEREBY PRODUCING RELAXATION-TYPE OSCILLATIONS; AND MEANS INCLUDING A VOLTAGE DIVIDING NETWORK FOR IMPRESSING A SYNCHRONIZING SIGNAL ON SAID DIODE HAVING A FREQUENCY DIFFERENT THAN THE REPETITION RATE OF SAID RELAXATION-TYPE OSCILLATIONS TO PRODUCE AN OUTPUT THEREFROM HAVING A FREQUENCY WHICH IS AN EXACT DIVISION OF THE FREQUENCY OF THE IMPRESSED SYNCHRONIZING SIGNAL.
