Design and Implementation of an Accurate 3-Bit System-on-Chip (SoC) Flash ADC for Aerospace Application in 90 nm CMOS Technology

摘要

Flash ADC is one of the fastest methods for analog to digital conversion. In the current project work, an accurate and improved low power flash ADC (analog to digital converter) has been designed for aerospace applications. The flash ADC has worked well with the consumption of low power and shows high accuracy in the system on chip (SoC) temperature sensor where we feed the analog output from the temperature sensor unit to the analog to digital converter. Process corner analysis has been performed to check for the robustness of the design. A power supply is + 1 to 0 V in the proposed design. The proposed design is better than previously designed ADCs in terms of power consumption, error and performance. Analysis for non-linearity (DNL and INL) has been done and graphs have been plotted for the same. The design and simulation have been tested with the help of Cadence Analog Design environment with UMC 90 nm CMOS process technology.
