Abstract :
In this project, a Flash ADC with TIQ(Threshold Inverter Quantizer) comparator and a Wallace tree encoder is described. Both DC and transient analysis report for 3 bit ADC are included. A comparison between Wallace tree and ROM encoder is included in the project illustrating how power can be reduced using Wallace tree encoder instead of ROM encoder. The design was successfully simulated for piece-wise linear and sinusoidal input. The 4 bit and 5 bit flash ADC with TIQ comparator and Wallace tree encoder is also described.
