Abstract:
A clock generation circuit for an integrated circuit device comprising:a temperature sensor circuit including a calibration circuit responsive to a temperature coding signal and a temperature sensor, the temperature sensor circuit having a first state in which a temperature output signal of the temperature sensor circuit is based on a temperature sensor output control signal and a second state in which the temperature output signal is based on the temperature sensor and the calibration circuit; a clock period controller circuit, including a calibration circuit responsive to period coding signal, that generates a period control signal based on the temperature output signal and the calibration circuit of the clock period controller circuit; and a clock generator circuit that generates a clock signal based on the period control signal; wherein the calibration circuit of the temperature sensor circuit comprises a plurality of fuses and wherein the temperature coding signal selects a state of ones of the plurality of fuses to calibrate the temperature output signal relative to an output of the temperature sensor; and wherein the first state or the second state of the temperature sensor circuit is selected based on the temperature sensor output control signal.
