Abstract
A power-on detection circuit for detecting a minimum operational frequency includes: an oscillating circuit, which includes: a ring oscillator, for generating a first oscillating signal; and a high pass filter for filtering the first oscillating signal to generate a second oscillating signal. The power-on detection circuit also includes a rectification device, coupled to the high pass filter, for generating a logic signal once the second oscillating signal reaches a certain frequency.
