Partitioned-charge-based modeling: a new approach

By taking moments of the hole (electron) continuity equation, a novel derivation of the partitioned-charge-based (PCB) bipolar junction transistor (BJT) model is presented. The derivation allows for an arbitrary partitioning of the excess charge in the quasi-neutral base (QNB) and thus generalizes the PCB methodology. With this novel approach, an optimal nonquasi-static (NQS) BJT equivalent network representation, within the PCB framework, can be obtained.<
