- 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.
