Abstract
Power-on reset circuits and methods for providing a power-on reset signal are provided. A first branch is configured to receive the power supply voltage. The first branch comprises a first current generator configured to generate a first current having a positive relationship with a power supply voltage. A second branch receives the power supply voltage and comprises a second current generator that is configured to generate a second current. A relationship between the first and second currents indicates whether the power supply voltage exceeds a threshold voltage of the power-on reset circuit. A current comparator circuit compares the first current to the second current and generates an output based on the comparison. The power-on reset signal is asserted when the output indicates that the second current is greater than the first current.
