The paper discusses the importance and the issues of interfacing capacitive sensors. Two architectures applicable for interfacing capacitive sensors are presented. The first solution was designed to interface a capacitive humidity sensor designed and built for a humiditydependent monolithic capacitor developed at Budapest University of Technology and Economics. The second case presents the poss...

Recent empirical and theoretical studies have shown that wireless links in low-power sensor networks are unreliable. Obviously, it is not a good choice for sensor networks that transmitting data unreliably, which will bring many problems to the networks, such as uncertainty, performance-decline, and so on. In this paper, a novel transmission strategy for reliable transmitting over unreliable li...

A new output structure for class E power amplifier (PA) is proposed in this paper. A series LC resonator circuit, tuned near the second harmonic of the operating frequency is added to the output circuit. This resonator causes low impedance at the second harmonic. The output circuit is designed to shape the switch voltage of the class E amplifier and lower the voltage stress of the transistor. T...

This paper take the principle of wireless communication with body implants to the implementation and testing stage. This paper describes a module that can fit into an implant case and results of testing a wireless link with a body model. Keywords—Clinical applications, low-power communication, miniaturisation, wireless.

One of the most compelling issues in the design of wireless communication components is to keep power dissipation between bounds. While low-power solutions are readily achieved in an applicationspecific approach, doing so in a programmable environment is a substantially harder problem. This paper presents an approach to lowpower programmable DSP that is based on the dynamic reconfiguration of h...

Although division is less frequent than addition and multiplication, because of its longer latency it dissipates a substantial part of the energy in floating-point units. In this paper we explore the relation between the radix and the energy dissipated. Previous work has been done on radix-4 and radix-8 division. Here we extend this study to a radix16 scheme with two overlapped radix-4 stages a...
