builder.resid.resid.OpAmp

final class OpAmp
extends Object

This class solves the opamp equation when loaded by different sets of resistors. Dag Lem wrote equations and the first implementation. This class is a rewrite without the use of fixed point integer mathematics and uses the actual voltages instead of the normalized values.
