Question

Find the The´venin equivalent representation of the circuit shown if gm = 0.025 S and R1 = 10 kΩ.

R1 Emv
Transcribed Image Text:R1 Emv
Expert Solution
Step 1

Consider the given figure:

The circuit current is -gmv

Write the expression for the voltage across the resistor.

v=IR1

v=-gmvR1

v+gmvR1=0

v(1+gmR1)=0

From the above, it is concluded that (1+gmR1) is not equal to 0 which means v is equal to 0.

Apply KVL:

-vi+v+vth=0

-vi+0+vth=0

vth=vi
