Question 1:

  1. For the circuit in figure 2 what is the gain from the input source, W1, to the output seen at the inverter output?

Answer 1:

 After analyzing the transient response of the circuit in figure 2:

We can notice that the amplitude of the input signal is approximately equal with the amplitude of the output signal, with a phase difference of 180 degrees, therefore we can conclude that the gain of the circuit is -1.

 Question 2:

  1. Which components determine the gain of the circuit in Figure 2?

Answer 2:

                The gain of the single stage amplifier in figure 6 is determined by the resistors R1 ad R2, having the following formula:
