Temperature sensor with high sensitivity in diode current source adjustable

摘要

b temperature sensor with high sensitivity du00ecodo with adjustable current source d a temperature sensor with high sensitivity diode includes a diode in reverse bias.As a Schottky diode, coupled to an adjustable constant current source to polarize the diode in a region of reverse operation.The constant current source polarizes the diode in a reverse leakage current that corresponds to a specific temperature window on which the voltage through the diode is reverse UMa linear response of several hundreds of MV / C. The change in reverse voltage can be used as a signal for switching power to an electrical load model.It is also revealed a temperature controller switching point double incorporating the temperature sensor with high sensitivity diode with a control circuit of feedback that permIte that the controller switch power to a load in two fixed points are adjustable using the temperature sensor only.
