Abstract
A miniature thick-film hybrid voltage multiplier comprising a metallized ceramic substrate, silicon diodes, and wire bonded electrical connections. The ceramic metallization patterns provide the required capacitors, appropriate diode soldering areas, and most circuit connections. The remaining circuit connections are made by bonding wires to provide for either series or parallel multiplier circuit arrangements.
Claims12
A voltage multiplier device of the type having capacitors connected in a first and a second series, and having diodes bridging between said series, said device comprising
- at least one dielectric substrate with upper, lower, and side surfaces,
- a plurality of discrete metallized upper plates on said upper surface,
- a plurality of discrete metallized lower plates on said lower surface,
- said upper plates being aligned with said lower plates to form pairs of upper and lower aligned plates, each pair of aligned plates acting with the intervening substrate to form a capacitor,
- a plurality of metallized paths
- each said path connecting the upper plate of one said pair to the lower plate of an adjacent said pair so as to connect said capacitors in one of said first and second series,
- each said path extending from said upper to said lower surface across said side of said substrate, thereby forming a plurality of discrete metallized paths extending across said side, and
- a plurality of diodes connected between said first and second series, said diode connections being made directly to and only to said upper metallized plates so that diode connections are made to only one surface of said substrate.
