WebA bipolar junction transistor (BJT) is a type of transistor that uses both electrons and electron holes as charge carriers. In contrast, a unipolar transistor, such as a field-effect … WebThe presence of a BJT in a circuit is described to Spice through the Spice input file using an element statement beginning with the letter Q. If more than one transistor exists in a circuit, then a unique name must be attached to Q to uniquely identify each transistor.
