Abstract :
A built-in parametric measurement circuit is proposed for time-interval measurement and set-up/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 imperfection, 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 set-up/hold time measurement show the practicality of the proposed unit
