Creation and Simulation of a Capacitance Multiplier circuit with TINA

In this tutorial video we will present how to create and simulate a “Capacitance multiplier” circuit using TINA.  A “capacitance multiplier” circuit can increase the effective value of a small capacitor C1 to a much larger value.

The capacitance seen at Vout is: Cout = C1 * R1/R3. The output capacitance can be verified by placing an AC source in series with a resistor tied to Vout and running an AC frequency response analysis.

We will show later on that the circuit behaves as if the C1 capacitor were multiplied by 1000, in the the R1C1 low pass circuit.
