The circuit used in this configuration is shown in the figure. RG is the generator resistance and RL is the load resistance.
Note: to make easier the use of the next formulas the index "c" in the hybrid parameters were suppressed. Instead write h22c in the next formulas we are using only h22.
Formula 1
Current gain:
GI = Ie / Ib
G1 = h22 / (1 + h22 x RL)
Where:
GI is the current gain
Other parameters as defined in table (MA096E).
Formula 2
Voltage gain:
Gv = Vce / Vcb
Where
Gv is the voltage gain
Other parameters as defined in table (M096E).
Formula 3
Input resistance:
Rin = Vcb / Ie
Rin = ( h11 + det h x RL ) / ( 1 + h22 x RL )
Where
Rin is the input resistance in ohm (Ω)
Other parameters as define in table (MA096E).
Formula 4
Output resistance:
Rout = Vce / Ie
Rout = (h11 + RG) / (det h + h22 x RG)
Where
Rout is the output resistance in ohm (Ω)
Other parameters as defined in table (MA096E).
Formula 5
Power gain:
Gp = (h212 x RL) / [ ( 1 + H22 x RL ) x ( h11 + det h x RL ) ]
Where
Gp is the power gain
Other parameters are defined as in table (MA096E).
Formula 6
Power gain with impedance matching:
Gp = ( 4 x RG x RL x h212 ) / [ Rg(1 + h22 x RL) x (h11 + det h x RL ) ]2
Where
Gp is the power gain
Other parameters as defined in table (MA096E).
