Abstract:
1. Circuitry including: first and second transistors which form a transistor pair, with each of the transistors including base, emitter and collector regions and a doped polysilicon emitter contact together with a metal contact and a metal interconnect, with the metal interconnect making an electrical connection to the emitter region by way of the metal contact and the polysilicon emitter contact, and with the metal interconnect being displaced laterally away from the emitter region so that no part of the metal interconnect overlies any portion of the emitter region; and wherein the transistor pair form part of circuitry selected from the group consisting of (a) differential transistor pair circuitry, (b) current mirror transistor pair circuitry and (c) voltage reference transistor pair circuitry.
