One could control temperature of the 3904 with a peltier if needed. silicon bandgap temperature sensor https://en.wikipedia.org/wiki/Silicon_bandgap_temperature_sensor https://en.wikipedia.org/wiki/Silicon_bandgap_temperature_se... http://www.sensorsmag.com/sensors/temperature/temperature-sensor-tips-and-tricks-1439 http://www.sensorsmag.com/sensors/temperature/temperature-se...
