“…Therefore we have: It is clear from this figure that even under optimal magnitude/phase bit allocation for polar quantizer, the rectangular quantizer achieves a higher SQNR, when the input signal follows a Figure 12 The SQNR comparison between the 7Bi/7Bq uniform rectangular and (14-Bp)/Bp polar quantizers for a signal with uniform rectangular distribution; µrn is the normalized signal power Figure 13 The SQNR ratio between the 7Bi/7Bq uniform rectangular and (14-Bp)/Bp polar quantizers for a signal with uniform rectangular distribution; µrn is the normalized signal power 24 uniform rectangular distribution. This result was indeed expected, since a uniform rectangular signal better fits in a rectangular quantizer with less wasted quantized area on the complex plane.…”

“…The design aspects associated with this new approach include extensive digitization of functions that were traditionally designed in analog circuitry, reliance on builtin calibration/compensation that is typically based on digital processing, and a design-for-testability philosophy wherein a product's datasheet provides statistical distributions, rather than hard-limit based specifications, in order to minimize testing costs and maximize production yields. The architectural aspects of the digitally-intensive transceiver are not covered here, and may be found in [1], or in the Japanese translation of this book [2], as well as in [3]- [6] and in [25]. An example of a highly-integrated digitally extensive transceiver is shown in Fig.…”

SUMMARYDigital RF solutions have been shown to be advantageous in various design aspects, such as accurate modeling, design reuse, and scaling when migrating to the next CMOS process node. Consequently, the majority of new low-cost and feature cell phones are now based on this approach. However, another equally important aspect of this approach to wireless transceiver SoC design, which is instrumental in allowing fast and low-cost productization, is in creating the inherent capability to assess performance and allow for low-cost built-in calibration and compensation, as well as characterization and final-testing. These internal capabilities can often rely solely on the SoCs existing processing resources, representing a zero cost adder, requiring only the development of the appropriate algorithms. This paper presents various examples of built-in measurements that have been demonstrated in wireless transceivers offered by Texas Instruments in recent years, based on the digital-RF processor (DRP TM ) technology, and highlights the importance of the various types presented; built-in self-calibration and compensation, built-in self-characterization, and builtin self-testing (BiST). The accompanying statistical approach to the design and productization of such products is also discussed, and fundamental terms related with these, such as 'soft specifications', are defined. key words: system-on-chip (SoC), digital RF processor (DRP), design for testability (DfT), design for manufacturability (DfM), built-in self-testing (BiST), soft specifications

“…The adoption of Muli-tap Direct Sampling Mixer (MTDSM), proposed recently by R.B. Staszewski, et al [2], is one of promising approaches for SDR. However, the conventional MTDSM consists of passive components, thus large gain loss and low order of the filter are unavoidable problems.…”

Abstract-This paper proposes a novel direct sampling mixer (DSM) using Switched Capacitor Filter (SCF) for multi-band receivers. The proposed DSM has a higher gain, more flexibility and lower flicker noise than that of conventional circuits. The mixer for Digital Terrestrial Television (ISDB-T) 1-segment was fabricated in a 0.18 µm CMOS process, and measured results are presented for a sampling frequency of 800 MHz. The experimental results exhibit 430 kHz signal bandwith with 27.3 dB attenuation of adjacent interferer assuming at 3 MHz offset.
