1. What is G22 Parameter?

G22 Parameter is the input impedance parameter in two-port network analysis. It represents the impedance seen at port 2 when port 1 is open-circuited.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( G22 \) — Input impedance parameter (Ohm)
• \( Y22 \) — Driving point admittance at port 2 (Siemens)

Explanation: The G22 parameter is simply the reciprocal of the Y22 parameter, representing the impedance-admittance relationship in two-port networks.

3. Importance of G22 Parameter Calculation

Details: Accurate calculation of G22 parameter is crucial for analyzing two-port networks, designing impedance matching circuits, and understanding network behavior in various electronic applications.

4. Using the Calculator

Tips: Enter Y22 parameter value in Siemens. The value must be positive and non-zero for valid calculation.
