In the high-resolution analog circuit, performance of chips is an important part. The needs to be determined by testing. According test requirements, stimulus signal with better quality and necessary. main research direction how generate high-speed when there no suitable digital-to-analog converter (DAC) chip available. this paper, we take analog-to-digital (ADC) as example; article uses DAC mu...

The demand for ever higher data rates is driving research for broadband wireless communications to data rates of 100 Gbit/s and beyond. This workshop presents research work on 100 Gbit/s wireless communications that uses carrier frequencies beyond 200 GHz with bandwidths of 20 GHz or more and moderate spectral efficiencies. Various wireless system and component design aspects are covered includ...

1 This paper describes a real-time signal processing system based on an Arti cial Neural Network chip, which has been developed for and tailored to non-linear control applications. The chip described, which uses Pulse Stream computation principles, has been designed and manufactured using a standard 1.5 m digital CMOS technology. The system can compute up to 140MCPS, with a Nyquist frequency of...

Standard electrophysiology experiments utilize a technique known as voltage clamping: the surface of the cellular membrane is held constant, or clamped, which allows the researcher to study the membrane permeability and ion exchange. This process is usually performed with commercially available analog equipment. While analog circuitry provides an accurate and reliable equipment medium, it does ...

We have demonstrated a digital receiver performing direct digitization of radio-frequency signals over a wide frequency range from kilohertz to gigahertz. The complete system, consisting of a cryopackaged superconductor all-digital receiver (ADR) chip followed by room-temperature interface electronics and a field programmable gate array (FPGA) based post-processing module, has been developed. T...

The adoption of digital signal processing (DSP) microchips for detection and analysis of electrocardiographic signals offers a means for increased computational speed and the opportunity for design of customized architecture to address real-time requirements. A system using the Motorola 56001 DSP chip has been designed to realize cycle-by-cycle detection (triggering) and waveform analysis using...
