Abstract
A method and apparatus is provided for measuring circuit parameters by analyzing an electric circuit. An equivalent circuit thereof is entered which comprises elements having element values thereof, and a break point and a virtual ground are specified in the equivalent circuit where the break point is provided for disconnecting an electric path for forming a closed-loop circuit. Then, a 2-port network is generated by disconnecting the electric path at the break point in the entered equivalent circuit to form first and second terminals that are ends of the electric path, where the 2-port network has a first port comprised of the first terminal and the virtual ground, and has a second port comprised of the second terminal and the virtual ground. Furthermore, S-parameters of the generated 2-port network is calculated, and an open-loop transfer function of the electric circuit is calculated according to the calculated S-parameters.
