A High Speed, Power Efficient, TIQ Based 3-Bit Flash ADC Having Multiplexer Based Encoding Scheme

Analog to digital converter has become matchless component in the applications which incorporate the real world continuous signal with the digital processors. Since processing of digital data is forging ahead over processing of analogue data, the usefulness of ADC’s also increases. The flash ADC which also called direct conversion ADC has a series of comparator, which operates in parallel to carry out high conversion data rate of the applied input signal. This paper proposed an adequate high speed 3-bit ADC which having TIQ comparator and an encoder which is made by using multiplexer. The approach of Threshold Invert Quantize comparator has also been introduced as an alternative of conventional comparator. The proposed design consumes average power of 54.6µW the input frequency of design is 10MHz which can be increased up to 15MHz and supply voltage of 0.7v.
