Figure: CE Transistor Circuit

To obtain the Hybrid model for transistor consider the CE circuit displayed in figure. The variables are iB, ic, vB(=vBE) and vc(=vCE). iB and vc are considered as a independent variables.


vB= f1(iB, vc )    ----------------------(1)                                    

iC= f2(iB, vc )    ----------------------(2)

By making a Taylor's series expansion around the quiescent point IB, VC and neglecting higher order terms, the following two equations are acquired.

ΔvB = (∂f1/∂iB)Vc . Δ iB + (∂f1/∂vc) IB. ΔvC --------------- (3)

Δ iC = (∂f2/∂iB)Vc . Δ iB + (∂f2/∂vc) IB. ΔvC ---------------- (4)
