11.4 Performance Analysis and Propagation Delay Time Estimation of Logic Families with HBTs ",J.del Pino, A.Hernández, J. García, B.González and A. Nunez - Centre for Applied Microelectronics. University of Las Palmas (Spain).

Abstract - A study of the operation and performance of ECL and CML families implemented with HBTs has been carried out. We have analyzed, by simulation, the behaviour of both logic families and compared their performances with other high-speed FET based families. As in silicon BJT-based circuits compared with CMOS, the HBT-based families are faster but more power is consumed with regard to the other FET families. We have also developed timing models expressed with simple equations. These equations are technology dependent and predict the timing operation of logic circuits as function of load capacitances and of fan-out. It fits well the behaviour of the gates against HSPICE simulations with errors smaller than 4% in all studied cases.
