4 HIGH SPEED SAMPLING AND HIGH SPEED ADCs , Walt Kester
High speed ADCs are used in a wide variety of real-time DSP signal-processing applications, replacing systems that used analog techniques alone. The major reason for using digital signal processing are (1) the cost of DSP processors has gone down, (2) their speed and computational power has increased, and (3) they are reprogrammable, thereby allowing for system performance upgrades without hard...
متن کاملTrend of High-Speed SAR ADC towards RF Sampling
One emerging trend of high-speed low-power ADC design is to leverage the successive approximation (SAR) topology. It has successfully advanced the power efficiency by orders of magnitude over the past decade. Given the nature of SAR algorithm, the conversion speed is intrinsically slow compared to other high-speed ADC architectures, and yet minimal static power is required due to the mostly dig...
متن کاملHigh Speed Under-Sampling Frequency Measurements on FPGA
Received Feb 10, 2017 Revised May 6, 2017 Accepted May 21, 2017 A Sampling rate is less than Nyquist rate in some applications because of hardware limitations. Consequently, extensive researches have been conducted on frequency detection from sub-sampled signals. Previous studies on under-sampling frequency measurements have mostly discussed undersampling frequency detection in theory and sugge...
متن کاملHigh-speed optical sampling using a silicon-chip temporal magnifier.
We demonstrate a single-shot technique for optical sampling based on temporal magnification using a silicon-chip time lens. We demonstrate the largest reported temporal magnification factor yet achieved (>500) and apply this technique to perform 1.3 TS/s single-shot sampling of ultrafast waveforms and to 80-Gb/s performance monitoring. This scheme offers the potential of developing a device tha...
متن کاملTerminology for High - Speed Sampling - Oscilloscope Calibration Dylan
We discuss procedures for calibrating high-speed sampling oscilloscopes at the National Institute of Standards and Technology, and the terminology associated with those calibrations. The discussion clarifies not only the calibration procedures, but how to use the calibrations to perform traceable oscilloscope measurements.
