摘要：A reference current generator circuit for generating a reference current I.sub.Rthat is independent of variations in the base- to-emitter junction voltages V.sub.BE of thetransistors in the generator circuit. Applying the reference current I.sub.R to a currentsource transistor Q. sub.CS in a CML circuit generates a collector current I.sub. O, outputby the current source transistor Q.sub.CS, that is independent of the variations in thebase-to-emitter junction voltages V.sub.BE of both circuits. This produces a CML outputvoltage V.sub.O that is nearly temperature independent. Combining the referencecurrent generator circuit with a current source transistor provides a constant and stablecurrent source that can be utilized in a variety of electronic circuit applications.
