- Homework Statement
- Determinate the equilibrium points of an OVA-Opamp circuit

Tell if this points are stable or not

- Relevant Equations
- Kirchhof's Laws

Hi everyone, I need help with this exercise becouse I don't know how to calculate the equilibrium points of a circuit. The original exersice is the following:

Assume that the open loop dynamic response of the OVA-opamp gets captured by Fig. 1(a) and

consider the circuit of Fig. 1(b).

Consider first that vs =0

Replace the opamp in Fig. 1(b) by the model of Fig. 1(a) with ideal diodes. Obtain the driving-

point characteristics seen by the capacitor . Provide justified answers to

the following questions:

• How many equilibrium points has the circuit?

• Which of these equilibrium points are stable, and which are unstable?

I have attached a file with the representation of the circuits.

Thank you very much, everyone.
