"This textbook is designed for a second course on digital systems, focused on the design of digital circuits. It was originally designed to accompany a MOOC (Massive Open Online Course) created at the Autonomous University of Barcelona (UAB), currently available on the Coursera platform. Readers will learn to develop complex digital circuits, starting from a functional specification, will know the design alternatives that a development engineer can choose to reach the specified circuit performance, and will understand which design tools are available to develop a new circuit.- Provides textbook coverage for one-semester, second course on digital systems, focused on the design of digital circuits;- Explains how to develop complex digital circuits, starting from a functional specification;- Demonstrates which design tools are necessary to develop a new circuit;- Describes the main problems development engineers are faced with, during the process of developing a new circuit;- Uses applied examples of complex circuits, such as elliptic curve scalar product, image processing, finite field operations;- Includes numerous, solved-examples in-text, as well as end of chapter exercises;- Provides all necessary VHDL and C source files."

"The book discusses active devices and circuits for microwave communications. It begins with the basics of device physics and then explores the design of microwave communication systems including analysis and the implementation of different circuits. In addition to classic topics in microwave active devices, such as p-i-n diodes, Schottky diodes, step recovery diodes, BJT, HBT, MESFET, HFET, and various microwave circuits like switch, phase shifter, attenuator, detector, amplifier, multiplier and mixer, the book also covers modern areas such as Class-F power amplifiers, direct frequency modulators, linearizers, and equalizers. Most of the examples are based on practical devices available in commercial markets and the circuits presented are operational. The book uses analytical methods to derive values of circuit components without the need for any circuit design tools, in order to explain the theory of the circuits. All the given analytical expressions are also cross verified using commercially available microwave circuit design tools, and each chapter includes relevant diagrams and solved problems. It is intended for scholars in the field of electronics and communication engineering."

"Analog to Digital Converter (ADC) merupakan salah satu komponen yang sangat penting dalam kehidupan sekarang. Banyak jenis ADC telah diciptakan dan digunakan sekarang ini, salah satunya adalah Delta Sigma ADC. Delta Sigma ADC memiliki fungsi yang sama seperti ADC yang lain, namun sinyal digital yang dihasilkan sudah mengalami modulasi frekuensi Pulse Width Modulation (PWM). Sehingga nilai-nilai pada sinyal analog direpresentasikan dengan lebar dari sinyal digital yang dihasilkan. Desain rangkaian Delta Sigma ADC memanfaatkan metode oversampling dan tidak menggunakan metode Nyquist. Kelemahan dari metode ini adalah diperlukan banyak switch sebagai komponen sampling. Simulasi yang menggunakan desain rangkaian Delta Sigma ADC dengan menggunakan banyak switch telah dilakukan pada penelitian sebelumnya. Hasil yang diperoleh sangatlah baik, namun komponen aktif yang digunakan masih menggunakan komponen yang bersifat ideal. Komponen aktif berupa operational amplifier(op-amp) digunakan sebagain komponen utama dalam summing integrator yang dikombinasikan dengan sebuah switch sebagai bagian sampling. Pada skripsi ini dilakukan simulasi Delta-Sigma DC untuk frekuensi kerja pada 1MHz dengan menggunakan komponen aktif yang real yaitu op-amp dengan seri LT1819. Analisa matematis dilakukan untuk menentukan besaran komponen pasif yang digunakan. Berdasarkan analisa dan simulasi yang telah dilakukan diperoleh hasil bahwa LT1819 dapat digunakan sebagai komponen aktif pada desain Delta-Sigma ADC. Dengan besar gain yang diinginkan oleh sistem bernilai 1, dengan resistansi sebesar 100 ohm, maka diperlukan kapasistansi pada integrator sebesar 50mFarad dan kapasistor dengan besaran sebesar 0,38miliFarad.

Analog to Digital Converter (ADC) is a kind of electrical component which has important rule in daily life. Until now, there are alot of kind ADC which have invented and used, Delta-Sigma ADC is one of it. Delta Sigma ADC has function like the other ADCs, but the digital signal which produce by the system has modulated as frequency modulation Pulse Width Modulation (PWM). The Delta Sigma ADC is using oversampling methode and not using Nyquist methode. The weakness of this methode is, the circuit needs switch as the sampling component. The simulation which used alot of switches in the circuit design of Delta Sigma ADC has presented at the previous research.

The result is very good, unfortunately the design used ideal active component. Active component such as operational amplifiere (op-amp) is needed for the main component for the summing integrator which combined with a switch as a sampling part. In this scientific paper will be simulated Delta-Sigma ADC for 1MHz which use the LT1819 as the real active component. mathematical analysis, is needed to define the value of the pasive component The analysis and simulation results is LT1819 can be used as active component of Delta-Sigma ADC. To get value 1 for the gain, based one the mathematic analysis with 100 ohm as the resistance, so the system needs a 50miliFarad capacitance for the integrator and 0,38miliFarad capacitance for the feedback"
