DarlingtonCircuit102 IEEE TRANSACTIONS ON CIRCUITS AND SYSTEMS―I: FUNDAMENTAL THEORY AND APPLICATIONS, VOL. 46, NO. 1, JANUARY 1999 Darlington’s Contributions to Transistor Circuit Design David A. Hodges, Fellow, IEEE (Invited Paper) IDNEY Darlington’s name is well known to electronic circuit designers. He is credited with the discovery and initial demonstration in the early 1950’s of what ever since has been known as the Darlington transistor pair, or simply the Darlington transistor or Darlington pair. This episode provides another example of Sidney’s wide-ranging technical interests and his creativity addressed to the solution of real engineering problems. Early silicon transistors suffered from low values of common-emitter current gain , and large variations of from sample to sample. might range fro……
