    摘要: The present invention discloses a configurable process variation monitoring circuit of a die and monitoring method thereof. The monitoring method includes a ring oscillator, a frequency divider and a frequency detector. The ring oscillator includes a plurality of first standard cells, a plurality of second standard cells and a plurality of multiplexers. The ring oscillator generates an oscillation signal in a first mode or a second mode according to a selection signal. The frequency divider is coupled to the ring oscillator and divides the oscillation signal by a value to generate a divided signal. The frequency divider is coupled to the frequency divider and counts periods of the divided signal by a base clock to generate an output value where the output value is related to the process variation.
