To determine Calculate the voltage v o in the given circuit of Figure. Explanation Given data: The g -parameters are g 11 = 3 35 S , g 12 = 20 7 , g 21 = 800 7 , g 22 = 50 7 k Ω . The h -parameters are h 11 = 5 k Ω , h 12 = − 0.2 , h 21 = − 4 , h 22 = 200 μ S . The input source voltage v g = 30 mV . Refer to Figure given in the textbook. The internal source impedance Z g is 10 ohms. The load impedance Z L is 15 k Ω . Formula used: Refer to the table Terminated Two-Port Equation in the textbook. Write the general expression for g parameters of the two-port model of a network. V Th = g 21 V g 1 + g 11 Z g (1) Z Th = g 22 − g 12 g 21 Z g 1 + g 11 Z g (2) Here, g 11 is the open circuit input admittance, g 12 is the short circuit reverse current gain, g 21 is the open circuit forward voltage gain, and g 22 is the short circuit output impedance. Write the general expression for h parameters of the two-port model of a network. V 2 V g = − h 21 Z L ( h 11 + Z g ) ( 1 + h 22 Z L ) − h 12 h 21 Z L (3) Here, h 11 is the input admittance of the network, h 12 is the reverse voltage gain, h 21 is the forward current gain, and h 22 is the output impedance of the network. Calculation: In the given circuit of Figure, the Thevenin equivalent seen looking into the g -network model from the right side is determined as follows. Find Thevenin Voltage V Th : Substitute 30 mV for V g , 10 Ω for Z g , 3 35 S for g 11 , and 800 7 for g 21 in equation (1). V Th = ( 800 7 ) ( 30 mV ) 1 + ( 3 35 S ) ( 10 Ω ) = 1846.154 mV Substitute 10 Ω for Z g , 3 35 S for g 11 , 20 7 for g 12 , 50 7 k Ω for g 22 , and 800 7 for g 21 in equation (2). Z Th = ( 50 7 k Ω ) − ( 20 7 ) ( 800 7 ) ( 10 Ω ) 1 + ( 3 35 S ) ( 10 Ω ) = ( 50 7 × 10 3 Ω ) − ( 20 7 ) ( 800 7 ) ( 10 Ω ) 1 + ( 3 35 ) ( 10 ) { ∵ 1 k = 10 3 } = 5384

Z parameter

The Z-parameters that are the impedance parameters of a two-port network are defined by expressing the two-port voltages V1 and V2 in terms of two-port currents I1 and I2. The Z-parameters are calculated by open circuiting one of the two ports at a time …
