Transient analysis of lateral transistors for use in CHL circuits

Transient response of the lateral transistor under collector excitation with a constant emitter-base bias has been analyzed using the charge control model. The use of this analysis in the study of the switching behavior of CHL and CHIL circuits is indicated. The similarity of CHL switching with that in I/SUP 2/L circuits is pointed out. The dependence of the rise and storage times of the transistor on collector current has been studied. The storage time is found to decrease with the discharging collector current, whereas the rise time increases with the initial collector current. The storage time can be lower than the rise time. The contribution of the model time constants to the response time constant has been investigated.
