Circuit arrangement for the lowering of the threshold voltage of a diode configured transistor

摘要

The present invention relates a circuit arrangement for the lowering of the threshold voltage of a diode configured transistor comprising a mirror transistor, a first transistor and a second transistor, said mirror transistor and said first transistor having in common the gate electrodes in a circuit node, said second transistor being connected in a transdiode configuration and placed between the gate electrode and the drain electrode of said first transistor, and a current source being connected to the gate electrode of said first transistor and to the drain electrode of said second transistor, characterized by comprising a third transistor which is configured to receive a switching signal at its gate electrode and is connected between the drain and the gate electrode of said first transistor.
