Abstract
A power-on-reset circuit includes an execution circuit and a control circuit. The execution circuit includes a first input terminal connected to a power supply, a second input terminal and the first output terminal each initially are at a low level. The first output terminal transitions from the low level to a high level when the first input terminal and the second input terminal have a voltage not less than a predetermined voltage. The control circuit includes a third input terminal connected to the first output terminal, a fourth input terminal connected to the first input terminal, and a second output terminal connected to the second input terminal. The second input terminal transitions from the low level to the high level when a difference between the voltage at the first input terminal and the voltage at the first output terminal is greater than the predetermined voltage.
