Ie. Opris, SERIES RESISTANCE COMPENSATION IN TRANSLINEAR CIRCUITS, IEEE transactions on circuits and systems. 1, Fundamental theory andapplications, 45(1), 1998, pp. 91-94
The base resistance is often the primary limitation factor for the acc
uracy in translinear circuits. A general compensation technique for th
e extrinsic base resistance and the emitter series resistance is prese
nted in this paper. The applications discussed include proportional-to
-absolute-temperature (PTAT) temperature sensors and bandgap reference
s.
