Abstract

The main design blocks of Flash ADC includes the middle bit. The second MSB and LSB’s of output binary bits design of comparator, decoder and digital to analog convertor. The design of comparator is the most critical task in this paper because the performance of ADC depends on the choice of comparator. This paper describes the design of high speed FLASH ADC using clocked digital comparator with 4-bit resolution. Analog signal is characterized by the signal whose amplitude is continuously changing with respect to time. The clock digital comparator is designed in TSMC 0.18 μm CMOS are obtained depending on the value of middle bit, if the value of middle bit is 0 then multiplexer based decoder circuit select the upper bits (Right side bits of middle bit) and if value of middle bit is 1 then it selects lower bits (Left side bits of middle bit).
