All-Optical Measurement of Background, Amplitude and Timing Jitter for high speed pulse trains or prbs sequences using autocorrelation function

2006

We present a simple method for all-optical measurements of background, amplitude- and timing-jitter of ultra high speed pulse trains or prbs sequences using the jitter dependences of the intercorrelation-peak shape.

Bezpieczeństwo w zakładach karnych i aresztach śledczych : uwagi dotyczące unormowań i praktyki

2018

Formy pomocy osobom pozbawionym wolności zwalnianym z zakładów karnych i aresztów śledczych oraz osobom im najbliższym. Rozważania na tle wykonawstwa…

Przedmiotem niniejszych rozważań jest problematyka pomocy postpenitencjarnej świadczonej na rzecz skazanych i osób im bliskich. Obowiązek wsparcia materialnego i rzeczowego oraz innych form pomocy wynika z założeń kodeksu karnego wykonawczego. Pomoc taka jest świadczona przez organy Służby Więziennej, kuratorów sądowych oraz jednostki niezaliczane do sektora finansów publicznych w ramach specjalnego funduszu celowego. Funkcję kontrolną wydatkowania tych środków sprawuje Minister Sprawiedliwości oraz Rada Główna do Spraw Społecznej Readaptacji i Pomocy Skazanym. Pomoc postpenitencjarna to także ważny instrument państwa służący zwalczaniu lub ograniczaniu przestępczości oraz wspieraniu osób p…

Novel voltage-controlled conditioning circuit applied to the ISFETs temporary drift and thermal dependency

2003

This paper describes a novel conditioning circuit applied to ion-sensitive field-effect transistors/membrane-ion-sensitive field-effect transistors (ISFETs/MEMFETs) sensors. The novel conditioning circuit allows the sensor polarization with the needed either voltage or current required in each application, thanks to two completely independent voltage-controlled blocks (current and voltage blocks). The control of the voltage block is the most critical point in our design because the voltage block maintains the sensor feedback stable, avoiding the thermal and temporary drifts of the sensor feedback.

CMOS Capacitance-to-Time Converter-Based Interface for Differential Capacitive Sensors

2020

This paper presents pre-layout simulation results on a CMOS implementation of a capacitance-to-time converter-based electronic interface for differential capacitive sensors. Its simple architecture, comprising only three operational amplifiers (OA) and a digital mixer (inverted XOR gate) allows, by properly setting the values of seven biasing resistors, to fit the working range anywhere from few fF to hundreds of pF, giving the output quasi-digital signals (T and PW) in the useful μs-ms range (appropriate for direct interfacing with general purposes microcontrollers). A couple of illustrative examples are provided.

Novel constant current driver for ISFET/MEMFETs characterization

2001

Abstract In the present work a new constant current driver for ISFETs and MEMFETs sensors has been developed. The proposed circuit maintains the ISFET/MEMFET operation point at constant drain–source current and voltage. The combination of some programmable current sources and an appropriate selection of a simple precision resistor allow a good ISFET/MEMFET polarization. The use of operational amplifiers with low offset and drift are required to provide the buffering function needed by the sensor.

Optoelectronic Module with Integrated Transceiver and Mux-Demux for Optical Interconnect Applications

2019

The design, development and improvtableement in electronic devices and components have led to the further miniaturization of the system devices and their interconnecting interfaces. Hence, reducing the size of the transmitter (Tx) chips, receiver (Rx) chips and associated components play an important role in designing a reduced/small sized optoelectronic modules for optical interconnect applications. Some of the associated components include multiplexer, demultiplexer, clock and data recovery circuits (CDR), etc. Therefore, in this paper we present an optoelectronic module with integrated transceiver (Tx-Rx) and multiplexer-demultiplexer (mux-demux) with the aim of reducing the total area o…

Basic Concepts of Power Distribution Network Design for High-Speed Transmission

2011

This paper tries to gather the Power Distribution Network (PDN) techniques used to preserve power integrity in PCB designs when transmitting data rates over 6 Gbps using the newest commercial optical modules. The PDN design described allows for proper impedance control of the power supply with the appropriate choice of the number, location and values of capacitors. This method needs the knowledge of the electrical RLC model of the regulators, copper planes, capacitors and vias used in the PCB. A particular case of PDN design will be presented for a module using one SNAP12 optical transmitter and one receiver connected to an Altera Stratix II GX FPGA. This board is designed to work with data…

Simulation of parasitic effects on Silicon Carbide devices for automotive electric traction

2020

Wide Band Gap (WBG) semiconductors are increasingly addressed towards Electric Vehicle (EV) applications, due to their significant advantages in terms of high-voltage and low-losses performances, suitable for high power applications. Nevertheless, the packaging in WBG devices represents a challenge for designers due to the notable impact that inductive and capacitive parasitic components can bring in high switching frequency regime in terms of noise and power losses. In this paper, a comparison between conventional Silicon (Si) and emerging Silicon-Carbide (SiC) power switching devices is presented. The effects of inductive parasitic effects and switching frequency are investigated in simul…
