Design of Low Power Encoder through Domino Logic for 4 Bit Flash Analog to Digital Converter in 90nm Technology using Cadence Tool

Rahul D. Marotkar | Dr. M. S. Nagmode ^[3]

Abstract: The paper proposes the low power encoder design for 4 bit flash analog to digital converter. The main important and challenging problems in the design of encoder are to convert the thermometer code into the binary code and more power consumption. In this paper, the encoder circuit converts the thermometer code into the gray code and then converts into the binary code. The proposed encoder is designed using domino logic to reduce the power consumption in 90nm technology with 1.2 V power supply using cadence tool. The simulation results are calculated and the average power consumption of the proposed encoder is 0.01728mW which is very useful for making high speed devices as compared to the current mode logic.
