Power-on reset circuit and method for low-voltage chips |
摘要 |
A power-on reset circuit and method for generating a reset signal according to the voltage of a power source. The circuit includes an oscillator for generating an oscillation signal. The frequency of the oscillation signal increases with the rising of the voltage of the power source. The circuit further includes a frequency detector for converting the oscillation frequency of the oscillation signal into a first output voltage, and includes a reset signal output circuit for outputting a reset signal according to the first output voltage. Therefore, the power-on reset circuit can be applied in low-voltage chips.
