Özet

This paper presents a calibrator circuit to minimize mainly the process parameter variations related problems of TIQ Based Flash ADC designs. The simulations are carried out using 0.35 mu CMOS technology in two directions; to correct the input analog range deviations, and to catch the possible missing codes due to process parameter and temperature variations. The designed TIQ based flash ADC core under calibration is 5b with the performance of 2Gs/s, and has a low power supply of 3.3V. However, the calibrator has power supply of 5V.
