Abstract
An improved voltage reference generator is provided. The voltage reference generator comprises: a first transistor having a gate electrode biased to place the first transistor in a weak inversion mode; and a second transistor connected in series with said first transistor and having a gate electrode biased to place the second transistor in a weak inversion mode, where the threshold voltage of the first transistor is smaller than the threshold voltage of the second transistor and the gate electrode of the second transistor is electrically coupled to a drain electrode of the second transistor and the source electrode of the first transistor to form an output for a reference voltage.
