Time-to-digital converters (TDCs) are increasingly used as building blocks in biomedical
imaging, digital communication, and measurement instrumentation systems. When …

On the basis of a generic mixed-signal system the scaling difficulties of analog and mixed-
signal circuits based on a signal representation in the voltage domain are discussed for …

Relatively few remains of Late Pliocene hominids' knapping activities have been recovered
to date, and these have seldom been studied in terms of manual dexterity and technical …

Abstract The realization of Software Defined Radio (SDR) requires flexible RF front-end to
accommodate multiple standards in different frequency bands. In this review paper, we …

The demand on telecom operators for new services and increased data rates has created
difficult requirements for the signal-to-noise-and-distortion ratio of wireless systems …

This paper presents a novel approach to design a digitally programmable low pass filter
(LPF) and variable gain amplifier (VGA) intended for a software-defined radio (SDR) front …

A software-defined radio (SDR) should theoretically receive any modulated frequency
channel in the (un) licensed spectrum, and guarantee top performance with energy savings …

In this paper, we propose a discrete-time IIR low-pass filter that achieves a high-order of
filtering through a charge-sharing rotation. Its sampling rate is then multiplied through …

A new broadband low-noise amplifier (LNA) is proposed in this paper. The LNA utilizes a
composite NMOS/PMOS cross-coupled transistor pair to increase the amplification while …

A novel mechanism for simultaneous multiple signal reception and transmission using
frequency multiplexing and shared processing. Multiple RF signals, which may be of various …
