Abstract
A circuit for measuring maximum operating frequency and its corresponding duty cycle for an input I/O cell implementation under test (IUT) includes a condition checking module, a central control module and a duty cycle measurement module. The condition checking module checks an upper threshold voltage and a lower threshold voltage. The central control module controls a plurality of operations for measuring the frequency. The duty cycle measurement module measures the duty cycle and finally all these modules together and calculates maximum operating frequency of the IUT.
