Abstract
A parameter setting circuit and method for an integrated circuit apply a pulse current to a pin of the integrated circuit during a programming mode of the integrated circuit, and then extract the difference between the voltage on the pin and the DC component of the voltage on the pin to determine a setting signal for parameter setting to an internal circuit of the integrated circuit. By this way, an input pin, an output pin or an input/output pin of the integrated circuit may be used as the pin implementing the parameter setting function.
