摘要:
A temperature sensor generates a digital representation of the temperature of the integrated circuit. A logic circuit reads the digital temperature and generates a multiple bit digital representation of an operational voltage and a multiple bit digital representation of a timing signal, both being functions of the integrated circuit temperature. A voltage generator converts the digital representation of the operational voltage to an analog voltage that biases portions of the integrated circuit requiring temperature compensated voltages. In one embodiment, the temperature compensated voltages bias memory cells. A timing generator converts the multiple bit digital representation of the timing signal to a logic signal.
