A MOSFET-only voltage source with arbitrary sign adjustable temperature coefficient

Rossi, Conrado - Oreggioni, Julián - Silveira, Fernando - Dualibe, Carlos

Resumen:

A MOS-diode biased by a constant inversion level current source is a simple MOSFET-only circuit that implements a voltage source with a linear temperature dependence. Through adjustment of the inversion level, the temperature slope may be changed from negative to positive, including the constant voltage condition. A test circuit, fabricated on a 0.35 μm CMOS technology, was measured from 300K to 375 K while sweeping the inversion coefficient from 0.06 to 180. The theoretical model agrees with the measured data, accurately predicting the temperature slope. The presented all-region continuous model is especially useful at and near zero temperature slope operation.
