FLIPPED GATE CURRENT REFERENCE AND METHOD OF USING

摘要

The present invention relates to a flip gate current reference and a method for using the same. The current reference includes a tracking voltage generator. The tracking voltage generator includes a flip gate transistor and a first transistor. The first transistor has a first leakage current. The first transistor is connected to the flip gate transistor in a Vgs subtractive arrangement. The tracking voltage generator further includes an output node configured to output a tracking voltage and a second transistor connected to the output node. The second transistor has a second leakage current. The current reference further includes an amplifier configured to receive the tracking voltage and output an amplified signal. The current reference further includes a control transistor configured to receive the amplified signal and allow reference current conduction. The current reference further includes a control register connected in series to the control transistor.
