ABSTRACT:
A temperature detector in an integrated circuit comprises a temperature-dependent voltage generator, a ring oscillator, a timer and a clock-driven recorder. The temperature-dependent voltage generator is configured to generate at least one temperature-dependent voltage. The ring oscillator is configured to generate a clock signal, which is affected by one of the at least one temperature-dependent voltage. The timer is configured to generate a time-out signal, which is affected by one of the temperature-dependent voltage. The clock-driven recorder has a clock input terminal in response to the clock signal and time-out signal.
