Abstract: This paper presents an 8-bit Flash ADC design based on Threshold Inverter Quantization (TIQ) comparators, replacing the traditional resistive ladder to achieve reduced area and enhanced speed. SAPON technology is employed to significantly lower power consumption. The design is implemented and simulated in 180nm CMOS technology using TANNER EDA, demonstrating improved efficiency suitable for high-speed, low-power applications.
