Threshold voltage fluctuation compensation circuit for FETS

摘要: This invention relates to a threshold voltage detection circuit for detecting the of field effect transistors (FETs) and semiconductor capable stable operation irrespective fluctuation by utilizing this circuit. The source-drain path first FET is connected in series with that second having substantially same as conductances these FETs are set predetermined ratio generate drop associated FET. can be used level-shifting. output connection applied gate constant current drain thus voltage.
