Reference voltage generator and circuit for measuring the threshold voltage of a MOS transistor, applicable to such a reference voltage generator

摘要

the present invention relates to a generator of reference voltage.;the generator is characterized in that it comprises two transistors (t 1 and t2 type mos transistor t2 and a channel which has a size of the same order of magnitude as the size correspondante of extension in relation to the source and the drain of the transistor of the space charge zone.the other dimension is small relative to the extension of the space charge zone and the other transistor t 1 is a channel with two dimensions are large in relation to the corresponding dimensionsthe extension of the space charge zone and means are provided for the difference of threshold voltages of transistors (t 1 and t2.the difference in threshold voltage from the reference voltage.;application to the feeding of large scale integrated circuits.
