Patent ID: 7256603

Claim:
An apparatus for measuring the static parameters of integrated circuits, used for testing the static parameters of a tested integrated circuit, comprising: a mode-selecting switch receiving at least one limiting signal and outputting one of the limiting signals according to a mode-selecting signal; a main control unit providing a testing signal to the tested integrated circuit according to one of the limiting signals; a current sampling unit obtaining the current flowing through the tested integrated circuit and outputting a current sampling signal; a voltage-sampling unit obtaining the voltage of the tested integrated circuit and outputting a voltage-sampling signal; a comparing unit comparing the current sampling signal and the voltage-sampling signal with the limiting signals to output a logic signal; a logic-judging unit receiving the logic signal and outputting the mode-selecting signal; and a feedback-selecting switch connected with the main control unit, the current sampling unit and the voltage-sampling unit, wherein the feedback-selecting switch outputs one of the current sampling signal and the voltage-sampling signal according to the mode-selecting signal.
