Time of flight (TOF) measurements in positron emission tomography (PET) are very challenging in terms of timing performance, and should achieve ideally less than 100ps FWHM precision. We present a time-based differential technique to read out SiPMs that ha ...
Design and optimization of a simple but efficient operational amplifier (OA) for switched-capacitor finite impulse response (SC FIR) filters are presented. The main design criteria are: proper characteristics for application in SC FIR filters, simplicity o ...
Subthreshold source-coupled logic (STSCL) circuits can be used in design of low-voltage and ultra-low power digital systems. This article introduces and analyzes new techniques for implementing complex digital systems using STSCL gates with an improved pow ...
This article presents a technique for improving the power-delay performance of subthreshold source-coupled logic (SCL) circuits. A source follower buffer stage is used at the output of each SCL stage. Analytical results confirmed by measurements in 0.18um ...

This research work deals with the design of linear CMOS RF power amplifiers. Two important aspects are treated: efficiency enhancement and frequency-tunable capability. For this purpose, two different integrated circuits were realized in a 0.11 µm technolo ...
We present a concept of "active material" with variable acoustic properties, being constituted of an electroacoustic transducer which acoustic impedance can be changed by an active mean. Among the different ways to obtain variable acoustic properties on an ...
The large subthreshold leakage current of static CMOS logic circuits designed in modern nanometer-scale technologies is one of the main barriers for implementing ultra-low power digital systems. Subthreshold source-coupled logic (STSCL) circuits are based ...
In this paper, the liner concept is an electroacoustic transducer which acoustic impedance can be changed by electrical means, be it passive or active. Among the different ways to obtain variable acoustic properties on an electroacoustic transducer's voici ...
The power system has been used for communication purposes for many decades, although it was mainly the power utility companies that used low bit rates for control and monitoring purposes. In the last ten years, however, the deregulation of the power and te ...
