    摘要: A selected bandgap reference (11) of a voltage generator (10) is operated at a duty cycle that is less than one hundred percent. The seclectable bandgap reference (11) has at a high current consumption when enabled and a low current consumption when disabled. The output voltage of the selectable bandgap reference (11) is stored on a storage element (13) when the selectable bandgap reference (11) is enabled. A high impedance amplifier (16) receives the stored voltage and generates the reference voltage.

    摘要: A Schottky diode capable of sustaining a breakdown voltage of greater than about 250 volts and a method for its manufacture. An epitaxial layer disposed on a semiconductor substrate has a thickness of at least about 15 micrometers and an impurity concentration ranging from about 1×1014 atoms per cubic centimeter to about 1×1015 atoms per cubic centimeter. A guard ring extends from about 3 micrometers to about 15 micrometers into the epitaxial layer. A dielectric material is formed over the epitaxial layer and a portion of the dielectric material is removed to expose a portion of the guard ring and a portion of the epitaxial layer within the guard ring. An electrically conductive material is formed over the exposed portion of the epitaxial layer and an electrically conductive material is formed in contact with a bottom surface of the semiconductor substrate.

    摘要: A power control system (25) uses two separate currents to control a startup operation of the power control system (25). The two currents are shunted to ground to inhibit operation of the power control system (25) and one of the two currents is disabled to minimize power dissipation. The two independently controlled currents are generated by a multiple output current high voltage device (12) responsively to two separate control signals (23,24).
