Book Description
This chapter provides an overview of design techniques and system aspects relevant to the application of high-speed pipelined ADCs in wireless base transceiver stations (BTS). The discussion begins with a derivation of typical ADC specifications for the receive path of a multi-carrier BTS system. Next, we investigate issues pertaining to the interface between the ADC and its driving circuitry, including complications that arise with sample-and-hold-amplifier-less (SHA-less) ADC frontends. Lastly, we summarize recent research results that look into the digital linearization of dynamic nonlinearities at the ADC’s frontend.

Book Description
In less than one decade after their introduction into radio-frequency applications, digital fractional-N phase-locked loops (PLLs) have become a relevant topic in microelectronic research and a practical solution for products. In addition to the well-known advantages, such as their silicon area occupation scaling as technology node and their easier portability to new nodes, digital PLLs enable easy and low-cost implementation of calibration techniques, which substantially reduce spurious tones and remove other major analog impairments. In wideband PLLs, the ultimate level of spur performance is often bounded by the time resolution and the linearity of the time-to-digital converter within the digital PLL. Methods for mitigating its nonlinearity such as those based on element randomization and large-scale dithering are discussed. The use of fractional-N dividers based on digital-to-time converters, as a means to relax the design of the time-to-digital converter, is also reviewed. This concept is extended to the limit case of a single-bit time-to-digital converter, which provides best PLL noise–power trade-off with good spur performance.

Book Description
This chapter offers a system-level analysis of advanced RF transceivers intended for use in wireless and particularly mobile applications. An overview of RF cellular standards is presented, followed by a discussion of various radio architectures. The key radio requirements are derived, and translated to circuit specs, giving an overview of a practical top-down radio design. Several radio non-idealities resulting from RF CMOS shortcomings are discussed, and various architectural and calibration techniques are introduced to overcome those. We will also cover more advanced topics such as handset calibration, the evolution to broadband, RF diversity, and next-generation mobile standards and their requirements.

Book Description
This chapter presents high-efficiency power amplifiers (PAs) for wireless infrastructure. It starts by stating the importance of high efficiency and the historical evolution in base station PA concepts. It then introduces the current solution, the Doherty PA. After explaining the fundamentals of the Doherty PA, a novel implementation achieving more than 35% drain efficiency across a 6dB power back-off range and up to 20W peak power between 1.7 and 2.3GHz is given. Afterwards, a future PA concept, switch-mode outphasing PA, is introduced. Theory and implementation details of a class-E outphasing PA achieving more than 60% drain efficiency across a 6dB power back-off range and up to 19W peak power between 1800 and 2050MHz is explained. By the end of the chapter, an essential part of switch-mode PAs, high voltage (up to 10V) and high frequency (up to 4GHz) drivers are presented.

Book Description
This paper reviews recent developments of interleaved Successive Approximation Analog-to-Digital converters (SAR) in deep sub-micron CMOS technologies. The discussion covers design tradeoffs and degrees of freedom related to the impact of extensive interleaving with many SAR units on bandwidth, noise, linearity, and spurious performance. The impact of interleaving mismatches on representative broadband and multi-carrier narrowband signals is also discussed. Next, two examples are given demonstrating how interleaving with many ADCs can be transformed from a weakness to a strength. The first example concerns low spurious performance enabled by redundant SAR converters and randomization of their operation. The second example presents spectral sensing techniques.

Book Description
This chapter presents one of the first integrated Ku-band downconverters with PLL frequency synthesizer that has widely penetrated the market of low noise blocks (LNBs) for reception of satellite television. It starts with a brief description of the general architecture of a LNB and a presentation of the main requirements for the integrated downconverter and frequency synthesizer. The architecture of the integrated circuit and the design of its building blocks are then presented and discussed in detail. The emphasis is put on the design choices made in the downconverter and the synthesizer for competing in cost and performance with discrete implementations at minimal power consumption. By the end of the chapter, measurement results are reported that illustrate the downconverter performance alone or within a demonstration LNB.

Book Description
This chapter discusses the practical application of RF digital-to-analog converters (RF DACs) to communication systems such as cable distribution, wireless communications infrastructure (WIFR) base stations, wireless backhaul, and other such systems. The key specifications that are driving the development of RF DAC technology are reviewed, as are some common radio architectures used to implement those systems. Challenges associated with the design of RF DACs are described, and some trade-offs and possible solutions are discussed. Design considerations of the package and the printed circuit board (PCB) design are reviewed. Measured results of an RF DAC suitable for cable head-end transmitters are presented. The features and performance of RF DACs provide an enabling solution for “Software Defined Radio” (SDR) systems targeted toward multi-carrier, multi-band, multi-standard radio transmitters.

Book Description
Radios for cellular wireless infrastructure require low-noise amplifiers (LNAs) with very demanding requirements on noise and linearity performance. So far these amplifiers have been realized in III-V technologies, but for various reasons silicon-based LNAs are needed too. This chapter will explain the challenges in LNA design for this application field.

Book Description
Time-to-digital converter (TDC) circuits are a key component for achieving high-performance digital phase-locked loops (PLLs) which offer lower area and greater flexibility than their analog PLL counterparts. This chapter focuses on a recently developed TDC architecture known as the gated ring oscillator (GRO) which offers first-order shaping of its quantization noise and delay stage mismatch. To provide context for the GRO discussion, background on general TDC implementation techniques is described along with key performance issues related to digital frequency synthesizers. The GRO concept is then presented, followed by implementation details and measured results. Finally, recent variations on the GRO concept are described such as a MASH TDC structure which achieves higher-order noise shaping and a switched ring oscillator (SRO) TDC which improves robustness to dead zones encountered by the GRO TDC.
