摘要： A differential output analog multiplier circuit utilizing four G4-FETs, each source connected to a current source. The four G4-FETs may be grouped into two pairs of two G4-FETs each, where one pair has its drains connected to a load, and the other par has its drains connected to another load. The differential output voltage is taken at the two loads. In one embodiment, for each G4-FET, the first and second junction gates are each connected together, where a first input voltage is applied to the front gates of each pair, and a second input voltage is applied to the first junction gates of each pair. Other embodiments are described and claimed.

摘要： An universal and programmable logic gate based on G4-FET technology is disclosed, leading to the design of more efficient logic circuits. A new full adder design based on the G4-FET is also presented. The G4-FET can also function as a unique router device offering coplanar crossing of signal paths that are isolated and perpendicular to one another. This has the potential of overcoming major limitations in VLSI design where complex interconnection schemes have become increasingly problematic.

摘要： An electronic circuit package in which several high voltage components are packaged along with low voltage components using standard circuit boards and minimizing the space needed for the entire assembly. A miniature circuit board, constructed of standard circuit board material, is used to mount several electronic components, some of which require high voltages. To meet isolation requirements, requiring a dielectric strength more than that provided by the board itself, between the high and low voltage nodes the circuit board incorporates slots or other cut out shapes in the board. The slots or other cut out shapes provide two functions. The first use for the slots or other cut out shapes is to prevent charge migration on the surface of the board between high and low voltage nodes. This is accomplished by placing the slots or other cut out shapes between high and low voltage nodes. The circuit board is then encapsulated within a potting material. The slots or other cut out shapes perform a second function of allowing the potting material to flow around and through the board to facilitate full encapsulation of the board and the electronic devices on the board. Several of the slots or other cut out shapes are placed in the board directly underneath the electronic devices mounted on the board to aid in allowing the potting material to completely surround and encapsulate the electronic devices.
