Ratiometric temperature stable current reference
Yann Deval, S.G. Ducouret, Jean P. Dom · Electronics Letters · 1993
Current-mode integraed circuit design leads to the use of a current reference achieving good temperature compensation. A novel circuit is described, which has good performance based on a ratiometric expression that is easily reproduced. As a bonus, the circuit acts as a PTAT (proportional to absolute temperature) reference without any structural change.
