Abstract

See full text

A transistor threshold extraction circuit having an output and including a first and a second transistor of the same type each having a control terminal and having essentially the same threshold voltage, the control terminal of the first transistor being connected to a constant potential node, a current mirror having at least one input terminal and one output terminal coupled respectively to said first and second transistors to provide bias currents, a first and a second potential reference, and a voltage divider having an intermediate tap and first and second end terminals. The control terminal of the second transistor is coupled to the intermediate tap and the divider is biased by coupling the first and the second end terminals respectively to the first and second potential references. The output is coupled to one of said end terminals.
