Description

From University Video Communications' catalog:

"The remarkably accurate exponential relationship between the collector current I(c) and base-emitter voltage V(BE) of a bipolar transistor is the foundation for many linear and nonlinear signal-processing circuits. This relationship results in the transcon-ductance dI(c)/dV(BE) being a linear function of collector current, whence the name translinear. This lecture begins by considering the physical origins of this behavior and its modeling, then presents and analyzes some basic translinear forms. Circuits containing closed loops of bipolar devices exhibit especially valuable properties; an important principle will be derived and illustrated with several examples, including wide band gain cells and multipliers."
