Abstract :
This paper presents simulations and measurements of an integrated PTAT sensor. The sensor is equipped with an overheat protection circuit and was implemented in an ASIC containing matrices of heat sources and junction temperature sensors. The PTAT sensor is used for temperature monitoring and it is responsible for issuing warning signals in a case of chip overheat. Particular attention is paid to the discussion of sensor design and the presentation of simulated circuit operation.
