PROBLEM TO BE SOLVED: To provide an intergal curve tracking circuit and a function generator for executing a Newton homotopy method. SOLUTION: This circuit has a first means for differentiating, sqauring, and adding a voltage data obtained from a measured circuit to be output, a second means for converting an output from the first means into a current source by a voltage control current source, a third means for assuming a voltage in a certain point to be sqaured and for converting it into a current by the voltage control current source, a fourth means for connecting a constant current source of 1 A (ampere) current in parallel, a fifth means for inserting in parallel a resistance of sufficiently high resistance to avoid cut-set of the current source, and a sixth means for integrating voltages obtained from both ends of the resistance inserted by the fifth means.
