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 = (h21^{2} 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 h21^{2} ) / [ 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).
