Electronic Circuit Design Ideas covers a wide variety of electronic circuit design, which consists of a circuit diagram, waveforms, and an explanation of how the circuit works. This text contains 14 chapters and starts with a review of the principles of digital circuits and interface circuits frequently used in circuit design. The next chapters describe the commonly used timer, op-amp, and amplifier circuits. Other chapters present some examples of waveform generators and oscillators used in circuit design. This work also looks into other classifications of circuits, including phase-locked loop, power-supply, and voltage regulator circuits. The final chapters are devoted to the methods of controlling DC servomotors and stepper motors. These chapters also examine other design ideas, specifically the use of slotted optical sensor based revolution detector, photodiode and magnetic transducer detector, and FSK circuit. This book will prove useful to electrical engineers, electronics professionals, hobbyists, and students.
