Opis

This book introduces a Gate Diffusion Input (GDI) methodology as an alternative approach in digital circuits. In this technique, a wide range of complex logic functions can be realized by using a lower number of CMOS transistors. The advantages of using GDI technique are multi-folded. The first is to implement digital gates (i.e. inverters, NAND, NOR, XOR, XNOR, buffers, etc.) with very low propagation delay and high logic level swing. As a second advantage, the GDI-based circuits consume lower power consumption and chip area compared with the CMOS equivalent. This provides a new implementation of digital circuits which are suitable for longer-lasting portable devices, like smartphones, tablets, IoT, etc.. A third advantage is the simplicity of circuit design by using very small cell library. In this book, after a brief review of GDI specifications, we will discuss different architectures of GDI-based digital circuits that have been recently proposed.
