Recently, interest has grown in using modest CMOS technology to achieve similar bit rates. This work achieves SONET OC-48 (2.488 Gbps) rates with 0.8 /spl mu/m CMOS technology. Because the data rate is near the process unity-gain frequency, a parallel architecture is used to demultiplex the data stream at the input. N precisely-spaced clocks that run at 1/N of the data rate are used. Instead of a conventional analog PLL that would require low noise sensitivity, this work explores oversampling each data bit and using digital logic to select the proper bit values. Although data is not sampled at the center of the eye, the digital loop can choose the best sample with bandwidth roughly the data transition rate.","PeriodicalId":162539,"journal":{"name":"1996 IEEE International Solid-State Circuits Conference.

In front-end RF circuits, however, trade-offs among six parameters have constantly challenged the designers: noise, power dissipation, linearity, voltage headroom, gain, and operating frequency. While upconversion mixers with supplies as low as 2 V have been reported, noise, speed, and supply rejection issues prohibit the use of such topologies for downconversion. This 900 MHz downconversion mixer employs circuit techniques to relax some of the above trade-offs. The fully-differential circuit consists of a core and an output buffer/amplifier, and operates from a 1.5 V supply.","PeriodicalId":162539,"journal":{"name":"1996 IEEE International Solid-State Circuits Conference.

Existing memory and ASIC processes have been optimized independently so there are well-recognized problems in seeking to combine memory and logic on a single chip. A number of applications demanding such a combination are emerging that warrant the design effort to overcome such problems. While processes better-suited to mixed memory and logic will become more generally available, the designer of an ASM today generally must find a way to add higher-density memory onto an ASIC chip, or, if a still greater capacity is needed, add efficient logic to a DRAM process. Neither task is as easy as it may seem.","PeriodicalId":162539,"journal":{"name":"1996 IEEE International Solid-State Circuits Conference.

It is a very application specific system on silicon, targeted at the standard definition TV receiver market (NTSC, PAL and SECAM). In the world of \"Systems on Silicon\" it is a rather unique system, since all signal processing is analog, while the control and adjustment signals are digital. As a product, it can be applied anywhere a standard TV receiving function is needed: TV sets, TV receiver plug-in cards for PCs, and so on. The current system is the result of a number of cooperating influences: market characteristics and set maker requirements, current TV standards, and capabilities of current silicon technology. In this paper these influences are explored and it is shown how they have shaped the present form of one-chip TV.","PeriodicalId":162539,"journal":{"name":"1996 IEEE International Solid-State Circuits Conference.
