Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
129 words
A VOLTAGE REGULATOR SENSING CIRCUIT COMPRISING: A NARROW JUNCTION DEGENERATE SEMICONDUCTOR DIODE DEVICE HAVING A PREDETERMINED PEAK CURRENT AND EXHIBITING A NEGATIVE RESISTANCE REGION IN THE LOW FORWARD VOLTAGE RANGE OF ITS CURRENT-VOLTAGE CHARACTERISTIC; MEANS FOR COUPLING SAID DIODE DEVICE TO A SOURCE OF ALTERNATING CURRENT VOLTAGE TO BE MAINTAINED AT A SELECTED LEVEL; MEANS COUPLED TO SAID DIODE DEVICE FOR AMPLITUDE MODULATING THE ALTERNATING CURRENT VOLTAGE APPLIED THERETO SO THAT THE SELECTED VOLTAGE LEVEL OF SAID ALTERNATING CURRENT VOLTAGE SOURCE THE PEAK CURRENT OF SAID DIODE DEVICE IS EXCEEDED ONLY FOR A PREDETERMINED PERIOD DURING EACH MODULATION CYCLE TO DEVELOP A DIRECT CURRENT VOLTAGE OUTPUT SIGNAL ACROSS SAID DIODE DEVICE WHICH DEPENDS IN VALUE UPON THE PEAKTO-PEAK DEVIATION FROM THE SELECTED LEVEL OF SAID ALTERNATING CURRENT VOLTAGE SOURCE.
