In the design of a 6-bit flash ADC, the designer decides to attempt to have equal contributions from all the sources of noise and distortion. The designer has identified 5 main sources (DNL, jitter, quantization, sampling noise, amplifiers distortion). Find the variance of these sources if the required ENOB is 5.5 bits. Please include a 30% margin in the design and assume a full-scale input signal of 1V peak-to-peak.
