A built-in parametric measurement circuit is proposed for time-interval measurement and setup/hold time measurement.The main idea is based on the dual-slope technique.The minimum resolution is set by resistor array configuration,which is 1/16 clock period in this paper and easily extendable to desired precision.The imperfectness,including the offset voltage and the settling time,is considered to improve the accuracy. Moreover a simple calibration method is proposed to reduce the measuring error.Experiments on the SRAM access time measurement and the register setup/hold time measurement show the practicality of the proposed unit.
