Discrete Fourier transform (DFT) implementation requires high computational resources and
time; a computational complexity of order O (N 2) for a signal of size N. Fast Fourier …

This paper presents a tutorial overview of ΣΔ modulators, their operating principles and
architectures, circuit errors and models, design methods, and practical issues. A review of …

Continuous mobile vision is limited by the inability to efficiently capture image frames and
process vision features. This is largely due to the energy burden of analog readout circuitry …

This paper presents a 10 bit successive approximation ADC in 65 nm CMOS that benefits
from technology scaling. It meets extremely low power requirements by using a charge …

This work introduces the use of compressed sensing (CS) algorithms for data compression
in wireless sensors to address the energy and telemetry bandwidth constraints common to …

This paper introduces a ΔΣ fractional-N digital PLL based on a single-bit TDC. A digital-to-
time converter, placed in the feedback path, cancels out the quantization noise introduced …

At the turn of this century, there was widespread concern that the performance of analog-to-
digital converters (ADCs) might have reached a saturation point and would, in fact …

A major hurdle to frequently performing mobile computer vision tasks is the high power
consumption of image sensing. In this work, we report the first publicly known experimental …

Software Defined Radio makes wireless communications easier, more efficient, and more
reliable. This book bridges the gap between academic research and practical …

A power-scalable SAR ADC for sensor applications is presented. The ADC features a
reconfigurable 5-to-10-bit DAC whose power scales exponentially with resolution. At low …
