  • Voltage comparator utilizing voltage to current conversion
    Patent number: 7626427
    Abstract: A voltage comparator for comparing a reference voltage with a threshold, includes a first voltage-to-current converter to convert a reference voltage that determines the threshold into a reference current that depends on the reference voltage, a second voltage-to-current converter to convert the comparison voltage into a comparison current that depends on the comparison voltage, and an output stage to output a digital output level, wherein the digital output level depends on the reference current and the comparison current.

  • Circuit array for limiting a load current by reverse phase angle control
    Patent number: 5331270
    Abstract: A circuit array, adapted to be coupled to a load and a source of a main AC voltage, for reverse phase angle control whereby a current flow in the load is limited to a defined phase angle (.alpha.) of the main AC voltage, comprising the following components for sequential control of the reverse phase angle control: a switching element, connected to the load and coupled to the source of the main AC voltage, for actuating the current flow in the load; a time determining component; and an integrated circuit.
