Beschreibung
Zusammenfassung:	A current reference which includes a tracking voltage generator including a flipped gate transistor, a first transistor connected with the flipped gate transistor in a Vgs subtractive arrangement, an output node providing a tracking voltage which has a positive or negative temperature dependency based on the flipped gate transistor and the first transistor, and a second transistor connected to the output node; an amplifier to receive the tracking voltage and output an amplified signal; a control transistor to receive the amplified signal; a control resistor connected in series with the control transistor; and a current mirror to receive and mirror a reference current to at least one external device, the current mirror including mirroring pairs having a corresponding mirroring resistor coupled in series with a corresponding mirroring transistor, the mirroring resistor of at least one of the mirroring pairs having a serpentine structure.
