R_{g} = ?

I_{1} = 0

(Rg = generator resistance)

The following formulas are used to determine the characteristics of the three transistors configurations.

**Formula 1 **

Output resistance:

V2 / I2 = 1 / h22

Where the quantities are the defined in table (MA096).

**Formula 2 **

Output conductance:

I2 / V2 = h22

Where the quantities are the defined in table (MA096).

**Formula 3 **

Voltage feedback:

V1 / V2 = h12

Where the quantities are the defined in table (MA096).

**Formula 4 **

Transfer inverse resistance:

V1 / I2 = h12 / h22

Where the quantities are the defined in table (MA096).
