  • Temperature detector and the method using the same
    Patent number: 8123404
    Abstract: A temperature detector comprises a first current mirror, a second current mirror, a first pulse generator, a second pulse generator, a phase detector and a controller. The current of the first current mirror is in variation with temperature, but the current of the second current mirror is not. If the output pulse of the first pulse generator appears earlier than that of the second pulse generator, the controller enhances the output current of the second current mirror. If the output pulse of the first pulse generator appears later than that of the second pulse generator, the controller decreases the output current of the second current mirror.

  • Temperature detector and the method using the same
    Patent number: 8096706
    Abstract: A temperature detector includes a plurality of comparators, an electronic component and a controller. Each of the comparators is responsible for detecting different temperature ranges. The electronic component has a temperature-dependent threshold voltage and an output connected to inputs of the plurality of comparators. The controller is configured to enable only one of the comparators at one time and to generate a value to the other inputs of the plurality of comparators.
