Using just two NAND or inverter gates its possible to build a D type (or ‘toggle’) flip-flop with a push-button input. At power-up the output of gate N2 is at a logical ‘1’, ensuring that transistor T2 ...

This repository contains the design and simulation of NOT, OR, AND, NAND, and NOR logic gates using PMOS, NMOS, and CMOS transistors in LTspice XVII. It demonstrates how basic and universal logic ...

CMOS NAND Gate design implemented using Cadence Virtuoso including schematic design, symbol creation, simulation, layout implementation and physical verification using DRC, LVS and REX. Digital logic ...

This is going to be a column that’s divided into three sections. It’s based on a question that a student posed in the EEWeb forums, and he also sent it directly to yours truly. The core of this ...

Abstract: The primary goal of this work is to develop a low-level physics-based nonquasi-static MOSFET model that can be extended to the simulation of high-level CMOS logic circuits. In this part of ...

Abstract: This paper comprehensively analyzes the schematic design, physical layout, and transient analysis of elementary CMOS logic gates, such as the NAND and inverter, in the Cadence Virtuoso ...

Density and speed of IC’s have increased exponentially for several decades, following a trend described by Moore’s Law. While it is accepted that this exponential improvement trend will end, it is ...
