A Low Power Decoding Circuitry for a Multi Channel Data Acquisition System using Gate Diffusion Input

G. Deepika; Dr. K. S. Rao

Multichannel data acquisition systems require a decoding circuitry for selecting each channel and this paper describes such circuit with a new technique - Gate Diffusion Input. This technique makes the logic design less complex, consumes very low power reduces the propagation delay and also the area. A combinational circuit for implementing a 4 to 16 decoder is designed and implemented using GDI AND gate. Dynamic threshold is employed in the design and operates with a power supply of ± 0.4V. The total power consumption is reduced by switching the power and was measured around 3.2µW.
