[...]... or recharge batteries Low cost implies simple circuits to minimize circuit area, but also low power dissipation to maximize battery life 1.2 Lower Frequency Analog Design and Microwave Design Versus RadioFrequencyIntegrated Circuit Design RFIC design has borrowed from both analog design techniques, used at lower frequencies [4, 5], and high -frequency design techniques, making use of microwave theory... examples, how linearity and noise issues arise xv xvi RadioFrequencyIntegrated Circuit Design In the latter part of the book, the RF circuits analyzed are ones that experience has shown to be good ones Concentration is on bipolar circuits, not metal oxide semiconductors (MOS) Bipolar still has many advantages at high frequency The depth with which design issues are addressed would not be possible if... in order to designradiofrequency (RF) communications integrated circuits (IC) in the gigahertz range, one must deal with transmission lines at chip interfaces and where interconnections on chip are far apart Also, impedance matching is addressed, which is a topic that arises most often in microwave circuits In my career, there has been a gap in comprehension between analog low -frequency designers and... 379 379 10.9 Class G and H Amplifiers 381 10.10 Class S Amplifiers 383 xiv RadioFrequencyIntegrated Circuit Design 10.11 Summary of Amplifier Classes for RF Integrated Circuits 384 10.12 AC Load Line 385 10.13 Matching to Achieve Desired Power 385 10.14 Transistor Saturation 388 10.15 Current Limits 388 10.16 Current Limits in Integrated Inductors 390 10.17 Power Combining 390 10.18 Thermal Runaway—Ballasting... xx RadioFrequencyIntegrated Circuit Design ´ Bill Toole, Jose Macedo, Sundus Kubba, Leonard Dauphinee, Rony Amaya, John J Nisbet, Sorin Voinegescu, John Long, Tom Smy, Walt Bax, Brian Robar, Richard Griffith, Hugues Lafontaine, Ash Swaminathan, Jugnu Ojha, George Khoury, Mark Cloutier, John Peirce, Bill Bereza, and Martin Snelgrove 1 Introduction to Communications Circuits 1.1 Introduction Radio frequency. .. for the designers to overcome As a result, the field of RFIC design should have an abundance of products to keep designers entertained for years to come This huge increase in interest in radiofrequency (RF) communications has resulted in an effort to provide components and complete systems on an integratedcircuit (IC) In academia, there has been much research aimed at putting a complete radio on... been devoted to designing radios using CMOS technologies [1–3] However, bipolar design continues to be the industry standard because it is a more developed technology and, in many cases, is better modeled Major research is being done in this area as well CMOS traditionally had the advantage of lower production cost, but as technology dimensions become 1 2 RadioFrequencyIntegrated Circuit Design smaller,... high-speed analog design in the context of microwave issues This is an advanced-level book, which should follow courses in basic circuits and transmission lines Most analog integratedcircuit designers in the past worked on applications at low enough frequency that microwave issues did not arise As a consequence, they were adept at lumped parameter circuits and often not comfortable with circuits where... low -frequency analog and microwave design is shown in Table 1.2 1.3 RadioFrequencyIntegrated Circuits Used in a Communications Transceiver A typical block diagram of most of the major circuit blocks that make up a typical superheterodyne communications transceiver is shown in Figure 1.1 Many aspects of this transceiver are common to all transceivers Table 1.2 Comparison of Analog and Microwave Design. ..
