This paper describes the design of an FSK transmitter for the 433 MHz ISM (Industrial, Scientific, Medical) band, which is realized in a standard digital 0.5 /spl mu/m CMOS technology. It includes the PA itself, an upconverter, and the circuit generating the baseband quadrature signals with a continuous phase modulation. The overall measured efficiency of the packaged circuit is higher than 38% for a 1.2 V supply and an output power reaching 10 dBm at 433 MHz.

In this paper, the design of an all-digital quadrature up and down converter with high accuracy and flexible IF settings is presented. The signal up/downconversion is achieved by interpolation/decimation combined with a programmable anti-alias filter preserving the selected frequency band during the sample rate conversion. This way a high-speed solution with low-power consumption is achieved. We used a novel technique to implement flexible IF settings. The resulting structure is capable of handling signals up to 160 MSPS and is suitable for coaxial access network modem applications.

The power dissipation associated with driving data buses can be significant, especially considering the increasing component of inter-wire capacitance. Previous work on bus encoding has focused on minimizing transitions to reduce power dissipation. In this paper, it is shown that transition reduction is not necessarily the best approach for reducing power when the effects of inter-wire capacitance are considered. An electrical model for data buses designed with submicron technologies is presented and a family of coding techniques is proposed that can reduce the average power consumption of the bus by 40%.

A /spl Delta//spl Sigma/ ADC designed in a 0.6 /spl mu/m CMOS process uses a reference voltage of only 1.0 V to provide a dynamic range of 142 dB and 132 dB in a bandwidth of 100 and 1000 Hz, respectively. The power optimized ADC implemented using a noise cancellation strategy has a noise floor of -168 dB, equivalent to the noise of a 1 k/spl Omega/ resistor. A reference ADC designed without a noise reduction mechanism has a noise floor of -148 dB. The high resolution converter targeted for sensitive instrumentation such as remote seismic monitoring and biomedical devices consumes 22.8 mW from a single 3.0 V supply.

Locally-clocked (LC) dynamic logic is an asynchronous circuit technique that uses an event-driven controller to moderate a fine-grained pipeline consisting of latching dynamic logic gates. This paper extends the methodology to include feedback between successive pipeline stages. LC dynamic logic's ability to handle feedback is illustrated with the design of a 660 MHz serial/parallel multiplier implemented in a 1 /spl mu/m, 5 V CMOS process.

During the nineties we have witnessed a string of advances in Silicon RF integration: from the introduction of the first integrated Si bipolar radios for GSM and DECT in the late eighties to the full single chip integration capabilities today using SiGe BiCMOS technologies. Where RF design used to be a black art, it is becoming a "normal practice" today.

This paper describes the S-TFT model developed for poly-Si TFT which improves the accuracy dramatically. The proposed model emphasis is on deriving the large parasitic resistance characteristics at low Vds by adding the junction current to the on-current. The physical-based subthreshold and off-state current model are also considered. The model guarantees the continuities of the current and the derivatives. Compared to the RPI model, known to be the best model, the proposed model improved overall simulation speed by 40-50% due to the better convergence characteristics.

This paper demonstrates new circuit technologies that enable a 0.25-/spl mu/m ASIC SRAM macro to be nonvolatile with only a 17% cell area overhead (NV-SRAM: nonvolatile SRAM). New capacitor-on-metal/via-stacked-plug process technologies make it possible for a NV-SRAM cell to consist of a six-transistor ASIC SRAM cell and two back-up ferroelectric capacitors stacked over the SRAM portion. A Vdd/2 plate line architecture makes read/write fatigue virtually negligible. A 512-byte test chip has been successfully fabricated to show compatibility with ASIC technologies.

This paper presents a single-chip cable upstream receiver which demodulates QPSK/16-QAM burst data in a frequency-agile, time-division multiple access (TDMA) scheme. An analog front end (AFE), an all-digital receiver and an FEC decoder are integrated on chip. The AFE performs coarse gain setting and signal quantization on either an IF input or baseband I/Q inputs. The digital QAM receiver contains a quadrature down-mixer, multi-stage decimators, Nyquist filters, carrier/timing acquisition loops, and an adaptive equalizer. The FEC decoder consists of a programmable descrambler and a versatile Reed-Solomon decoder. The chip occupies 4.7/spl times/7.8 mm/sup 2/ die area in a 0.35-/spl mu/m CMOS process, and consumes 1.0 W at 3.3 V in a 100-pin PQFP.

This paper discusses accuracy issues in parasitic extraction for the design of multimillion-transistor integrated circuits. The methodology reported aims at reducing the gap between the parasitic values estimated during implementation and the results of post-layout extraction. The objective is to obtain progressively refined interconnect models in hierarchical design flows. This methodology was developed for the 800 MHz UltraSPARC-III microprocessor. Our experimental results demonstrate the profound impact of the extraction methodology on interconnect modeling as well as subsequent timing and noise analyses.
