Colleagues,

Could you help me on this one? I want to build a bandgap temperature sensor based on a diode. Could anyone post a reference to a schematic and principles of operation?

... in the meantime I'll do some PSpice sims.

Thanks,
Nick

 

Here is a pretty good article on the broader topic of temperature sensors. It has a section on the basic bandgap temperature sensor.
