This book provides semester-length coverage of electronics for embedded systems, covering most common analog and digital circuit-related issues encountered while designing embedded system hardware.  It is written for students and young professionals who have basic circuit theory background and want to learn more about passive circuits, diode and bipolar transistor circuits, the state-of-the-art CMOS logic family and its interface with older logic families such as TTL, sensors and sensor physics, operational amplifier circuits to condition sensor signals, data converters and various circuits used in electro-mechanical device control in embedded systems.  The book also provides numerous hardware design examples by integrating the topics learned in earlier chapters.  The last chapter extensively reviews the combinational and sequential logic design principles to be able to design the digital part of embedded system hardware.
