WebL2 Autumn 2009 E2.2 Analogue Electronics Imperial College London – EEE 4 The small signal model the of BJT • The model below is useful to frequencies of up to 100s of MHz • The model is strictly valid for B-E voltage variations smaller than V T=25mV. • To analyse a circuit: – Each transistor in a circuit is replaced by this model – The “base spreading … WebThe BJT model is used to develop BiCMOS, TTL, and ECL circuits. For BiCMOS devices, use the high current Beta degradation parameters, IKF and IKR, to modify high injection effects. The model parameter SUBS facilitates the modeling of both vertical and lateral geometrics. Model Selection To select a BJT device, use a BJT element and model …
