Derive algebraic expression for a Thevenin\'s equivalent resistance RTH for this

Question

Derive algebraic expression for a Thevenin's equivalent resistance RTH for this amplifier circuit as seen at terminals a'-a from the emitter terminal E to the GND, including the resistor RE and all the other resistors in the circuit. Use a test source technique to complete your assignment. You may use a voltage-test- source or a current-test-source. You should try using a couple of different methods to solve the circuit (i.e. node voltages and loop currents). Show all your work. Arrange your final algebraic expressions in a meaningful way. Next calculate the value of the Thevenin's equivalent resistance RTH for this circuit. Given: vs(t)=0.1sin(377t) V, Rs=500 ohm , r pi =2.6k ohm , RE=100 ohm , RL=lk ohm , and beta =100

Explanation / Answer

To calculate Rth, we short circuit voltage sources and open current sources.

Hence, Rth = Rs + R = 500+ 2600 = 3100
