www.rfdesign.com February 2001 I today’s world of miniaturization, there is everincreasing industry pressure to reduce the cost of communication chips. This pressure has driven designers to develop transceivers with higher levels of integration1. Achieving the goal of maximum integration between the antenna and data output is not as trivial as replacing external components with on-chip componen...

There are certainly dozens of issues that will make the testing of mixed signal systems-on-a-chip (SOCs) difficult and costly. Many of these issues are the same ones that have been with the testing community for years. But there are a few testing issues that are either unique to mixed signal SOCs or at least are extremely exaggerated in these highly integrated designs. The problems fall into th...

UT Mixed-Signal Simulator is a mixed-signal, mixeddomain, and mixed-language design environment which supports VHDL-AMS 1999, VHDL-2002, Verilog 2001, SystemVerilog 2005 assertions, and SystemC 2005.

A set of low-power techniques is proposed to realize low power design in pipeline analog-to-digital converter (ADC). These techniques include removing the active S/H (i.e., SHA-less), sharing the opamp between the adjacent multi-bit-per-stages, low-power high-efficiency high-swing amplifier technique. Also, a new sampling topology is proposed to minimize aperture error by matching the time cons...

TECHNOLOGY In this paper, we report a manufacturable InP DHBT technology, suitable for medium scale mixed-signal and monolithic microwave integrated circuits. The MBE grown InP-based DHBTs with an emitter area of 1 × 4 μm exhibited peak cutoff frequencies (fT and fMAX) > 300 GHz, and a breakdown voltage (BVCEo) of ~ 5 V. The InP DHBT layer structures were grown on 3” semiinsulating InP substrat...

In this paper, an imaging chip for acquiring range information using by 0.35 μm CMOS technology and 5V power supply has been described. The system can extract range information without any mechanical movement and all the signal processing is done on the chip. All of the image sensors and mixed-signal processors are integrated in the chip. The design range is 1.5m-10m with 18 scales.

– Core-based testing, which is described by the proposed IEEE standard P1500, is an effective test method for Systems-on-Chip (SOC) containing embedded cores. This test method is usable for all classes of digital cores and provides solutions that allow automatic identification and configuration of testability features in SOC containing embedded cores. In this moment, IEEE P1500 is restricted to...

Perhaps the most well known of the propert ies that characterize chaotic systems is their sensitivity to initial conditions. Two identical chaotic systems that are started from virtually identical initial condi t ions in a short time would be observed to diverge f rom one another . However, for chaotic systems one observes a very impor tan t phenomenon called chaot ic synchronization. This is a...

in an attempt to develop alternative medicine for the treatment of diabetes and related complications, the antidiabetic potential of the fruits of c rataegus pinnatifida was evaluated. the antidiabetic potential of the methanol (meoh) extract as well as different solvent soluble fractions of the fruits of c . pinnatifida was evaluated via α-glucosidase, protein tyrosine phosphatase 1b (ptp1b), ...
