ABSTRACT:
A voltage is provided by a master circuit and received by a plurality of slave circuits over a bus. The master circuit includes a V.sub.bb reference circuit, a temperature compensation and V.sub.cse reference circuit, and a voltage step-up and buffering circuit coupled to the bus. Each of the slave circuits has a pair of transistors coupled to the bus in an emitter-follower configuration to step down the voltage from the master circuit and to provide a voltage reference. The voltage provided to the bus varies as it propagates through the bus. Accordingly, a plurality of unconnected resistors are formed in the portions of the silicon substrate which contain the master and/or slave circuits. When formed in the master circuit, the resistors are located in the V.sub.bb reference circuit. When formed in the slave circuit, the resistors are located in close proximity to the output transistors. One or more of the resistors may be selectively coupled to its respective master or slave circuit for compensating for voltage drops along the bus.
