A new realization of non-recursive digital filters using operation on ternary delta modulated signal is proposed. Direct operation on ternary delta modulated signal will be derived mathematically and a hardware implementation of ternary arithmetic operation will be shown. The primary advantage of the ternary scheme is the simplicity of the hardware and reduction in connections and interconnecti...

In this article, we present an efficient way of implementing 90° phase shifter using Hilbert transformer with canonic signed digit (CSD) coefficients in FPGA. It is implemented using 27-tap symmetric finite impulse response (FIR) filter. Representing the filter coefficients by CSD eliminates the need for multipliers and the filter is implemented using shifters and adders/subtractors. The simula...

A scaling-friendly and energy-efficient 0-1 MASH ΔΣ ADC is proposed in this work. An 8b SAR is used as the 1st stage for coarse quantization. A ring VCO is used as the 2nd stage for fine quantization. The proposed ADC uses digital background calibration to track VCO gain variation across PVT. A 40nm CMOS prototype achieves a Walden FoM of 18.5 fJ/conv-step while operating from 1.1V supply. Intr...

Two-dimensional finite impulse response (FIR) filters are an important component in many image and video processing systems. The processing of complex video applications in real time requires high computational power, which can be provided using field programmable gate arrays (FPGAs) due to their inherent parallelism. The most resource-intensive components in computing FIR filters are the multi...

While the functionality of emerging wireless microsensors, cellular phones, and biomedical implants, to name a few, is on the rise, their dimensions continue to shrink. This is unfortunate because smaller batteries exhaust quicker. Not surprisingly, recharging batteries wirelessly is becoming increasingly popular today. Still, small pickup coils cannot harness much, so induced EMF voltages vEMF...
