Abstract :
In this paper a new CMOS temperature compensated current reference circuit is proposed, which is accomplished by one first order temperature compensation and two current sources with opposite temperature coefficients, CTAT and PTAT. The CTAT current source compensates at low temperatures and the PTAT at high temperatures obtaining a smaller temperature coeficient.
