  • Patent number: 3992676
    Abstract: Conventionally, the common-emitter current gain h.sub.fe of a first transistor is reduced to a better-defined value -G by shunting the series connection of its base-emitter junction and emitter degeneration resistor with the series connection of a self-biased, second transistor and a further resistor. By including, per the present invention, a still further resistor in the collector-to-base connection of the second transistor, properly proportioned relative to the other resistors, a second-order dependence of -G upon h.sub.fe can be significantly reduced.

  • Patent number: 3931634
    Abstract: A junction-isolated monolithic integrated circuit device has its component elements connected in a circuit configuration such that at least one of the isolation PN junctions may be forward-biased at least part of the time, while other isolation junctions remain reverse-biased. To prevent detrimental parasitic transistor action which may result from the injection of carriers across a forward-biased isolation junction, means are provided for collecting those carriers at a location close to the injecting junction.
