Abstract:
Method and device for detecting the process corner of a transistor are provided. The process corner detection method includes providing a ring oscillator. The ring oscillator includes an odd number of oscillation units connected in series and an output port of one of the oscillation units serves as the output port of the ring oscillator to output an oscillation signal. Each oscillation unit is constructed based on a PMOS transistor and an NMOS transistor. The process corner detection method further includes measuring the period of the oscillation signal and the maintaining time of the oscillation signal at a high level and a low level in each cycle; and determining the process corner of the PMOS transistor and the NMOS transistor in the oscillation unit based on the period of the oscillation signal and the maintaining time of the oscillation signal at a high level and a low level in each cycle.

Claim (Index 3):
The method according to  claim 2 , wherein determining the process corner of the PMOS transistor and the NMOS transistor in the oscillation unit comprises:\n comparing the period of the oscillation signal with the first threshold value and the second threshold value to obtain a first comparison result, the second threshold value being less than the first threshold value; comparing the maintaining time of the oscillation signal at the high level and the low level in each cycle to obtain a second comparison result; and determining the process corner of the PMOS transistor and the NMOS transistor in the oscillation unit based on the first comparison result and the second comparison result.
