WebA bipolar junction transistor is a three-terminal semiconductor device that consists of two p-n junctions which are able to amplify or magnify a signal. It is a current controlled device. The three terminals of the BJT are the … WebA bipolar junction transistor parameter similar to β is “alpha,” symbolized by the Greek letter α. It is defined as the ratio between collector current and emitter current: α = I C I E α = I C I E. Apply algebraic substitution to this formula so that alpha is defined as a function of beta: α = f (β) α = f ( β).
