and promise to continue that growth for many years to come The year 2010 has already seen silicon CPU chips using more than 2 billion transistors and Moore s Law promises even larger transistor counts in the coming years Analog integrated circuits are becoming ever more sophisticated and important since they provide the very important function of interfacing many data acquisition and signal processing systems with purely digital computers In addition as mixed mode analog digital systems become more important in many consumer products such as cellular communications and wireless data acquisition systems the design and analysis of analog integrated circuits has become a very important requirement for many designers of VLSI systems One major component in many of today s analog electronic systems is the operational EE 140 ANALOG INTEGRATED CIRCUITS SPRING 2011 C Nguyen amplifier The op amp is used as a circuit block in systems such as analog to digital and digital to analog converters switched capacitor functions signal processing systems integrated circuit filters and virtually all systems where amplification of input signals is needed Indeed the op amp is probably the most commonly used analog circuit block As a result it is important for students interested in electronic circuit design and analysis to have a thorough knowledge of the design and analysis of the operational amplifier This course will examine the technology and circuit techniques associated with integrated monolithic amplifier circuits and the challenges that lie ahead in their development The goal is to achieve a basic understanding and knowledge of the driving and limiting factors in circuit performance of circuit design techniques and of fabrication techniques and technology issues important to integrated amplifier circuits in general and to op amps in particular The first part of the course reviews the small signal models of both Bipolar Junction Transistor BJT and Metal Oxide Semiconductor MOS transistors The course assumes that students have had a significant amount of experience in the analysis and design of discrete BJT amplifiers and some experience in the design and analysis of MOS amplifiers Consequently MOS amplifier stages will be emphasized initially and more lab experiments will be geared towards illustrating specifically the design of MOS amplifiers BJT and MOS multi transistor amplifiers are reviewed next with an emphasis on inspection analysis of multi transistor circuits After covering basic material on transistor amplifiers we will review the application of transistors in the design of various basic analog circuit blocks that are utilized in the implementation of a complete integrated operational amplifier circuit These circuit blocks include current sources and current mirrors level shifters active loads and differential amplifier stages These circuit blocks are needed in the design and analysis of many amplifier circuits and are particularly required for the design and analysis of op amps Although much of the lecture coverage will be on MOS op amp design you will assemble and design an operational amplifier in the laboratory using several different circuit blocks based on BJT devices which are more robust for use in a laboratory setting Since it is impractical to build an actual CMOS op amp in the laboratory using off the shelf components you will be given a design project that involves the design and simulation of a CMOS op amp using available CAD tools This laboratory will be a software lab assignment and will focus on the design tradeoffs involved in the design of CMOS op amps There will be no hardware labs during this time Note that the design project will be due before the end of the semester unless circumstances dictate otherwise An important topic in the design of any amplifier circuit is that of feedback and amplifier stability and this course will spend sufficient time discussing feedback and the use of feedback techniques to stabilize the response and performance of amplifier circuits The course concludes with coverage of some practical issues in analog circuit such as stability against variations in power supply and temperature for which supply and temperature independent bias references will be needed Lectures are intended to discuss and supplement the material in the text and the laboratory experiments A number of suggested reference books are listed below that should supplement the material not covered in the textbook Problem sets will attempt to emphasize important points Students will analyze and simulate circuits using SPICE and analyze problems related to fabrication of analog ICs Both hardware and software labs will be assigned to familiarize students with the design aspects of amplifier circuits in general and op amps in particular Lectures and discussion 4 units Prerequisites The prerequisites for this course are EE 105 and some aspects of EE 20N It is
