Analysis of digital DSP blocks using GDI technology

In parallel with enhancements in the technology of integrated circuits, transistors are implemented in silicon. Though the price is reduced; design is more complicated, which create the efficiency and power consumption. The reason why modern GDI-based circuit is the focus of attention is that in designing digital circuit, less power is required while more efficiency is obtained. Lowering the complexity of logic circuit can bring about reduction of power consumption, propagation delay and decrease circuit space. GDI-based integrated circuit resembles MOSFET transistors but have fewer transistors and higher performance capability. This study addresses two main areas which are Studying and investigating primary logic gate behaviors of NOR, NAND, OR, NOR, XOR, XNOR, INVERTER, that are used to employ CMOS, NMOS and GDI. Moreover, designing and analysis of FIR block which are done, using basic blocks implemented in the first stage. In this study, the design circuits-either basic blocks or FIR will be compared to NMOS and CMOS in terms of average power consumption, performance, and area occupancy.
