I'm trying to add an additional voltage output to a bandgap reference to output a PTAT voltage referenced to GND that can provide information on the temperature of the circuit. In other words, to provide a voltage whose slope = voltage/degree C. This output voltage will will need to be both Vdd and process independent. My idea is to take the PTAT current out of the PTAT block of the bandgap and use that somehow.
Does anyone have suggestions as to how I can best do this? Or can provide references?
