Abstract
A radar device (100) is described that includes at least one transceiver (105) configured to support frequency modulated continuous wave (FMCW); radar device (100) and a digital controller (262). A temperature sensor system includes a plurality of temperature sensors (222, 232, 242) coupled to one or more circuits (220, 230, 240) in the at least one transceiver (105). The digital controller (262, 306) comprises or is operably coupled to an over-temperature emulation circuit (308) configured to emulate an over-temperature shutdown state by injecting an over-temperature force signal (290) into the temperature sensor system (270).
