Simulation is the means of saving time and money, especially nowadays when the electronics have evolved in very fast steps, leading to the development of complex and rather costly devices and systems. PSPICE has been developed in 1975 to cope with complex circuit design of integrated circuits and this tool has been extensively utilized for simulation of huge electronic systems and super computing processes. The intention of this book is to provide guidelines to engineering students that are involved with digital and analog experiments and projects. The book targets several disciplines in Electrical engineering such as: Digital and analog low power circuits High power electronics Logic circuits design Transmission and reception
