Abstract

An electronic circuit for current generation includes a source-follower based current source and a voltage compensation semiconductor device. The source-follower based current source is configured to output a reference current, the current source including a main transistor which is configured to derive the reference current from a reference voltage, wherein the main transistor has a voltage drop that varies with temperature and process variations. The voltage compensation semiconductor device is configured to be biased with bias currents that increase the reference voltage provided to the main transistor by an offset voltage that matches the voltage drop of the main transistor across at least part of the temperature and process variations, thereby pre-compensating for the voltage drop of the main transistor.
