Abstract
  • This thesis describes the development of a flash analog-to-digital converter based on current-mode technique. The advantages of current -mode technique are higher speed, smaller chip area, and simple division of reference current based on current mirror. A current-mode comparator is designed consisting of a cascode current mirror and a current sense amplifier used as a latch. The new method allows effective and simple high-speed A/D conversion where the input is a current signal and the output of the latch is a digital voltage signal. A four-bit flash analog-to-digital converter, using current sense amplifier comparator is designed and simulated in 1-micron CMOS technology. Simulation results show that for ADC with resolution below six-bit, this technique offers a comparable accuracy with the existing voltage-mode methods at much higher speed.
