… vara handhållet. Vidare var det önskvärt att mätvärdet representerades med en analog visare, där mätintervallet skulle gå mellan 800 och 1200 W/m2. Efter litteraturstudier och informationssökning utfördes simuleringar i programmet LTSpice parallellt med prototypframtagning i …
implementering mot integrerade analoga kretsar
… and more complex and to keep low costs and power consumption, both digital and analog parts are implemented on the same chip. The degree of automization for the digital parts have increased fast and is high, but for the analog parts this has not come through. This have created a …
… be done, are done automatically today, but it can get better. Especially for analog circuit design. At Electronic System in Linköpings universitet, research is in progress to develop a tool that can design analog circuits in reasonable time. It means that it has to size the …
… we describe an adaptive simulated annealing method for sizing the devices in analog circuits. The motivation for use an adaptive simulated annealing method for analog circuit design are to increase the efficiency of the design circuit. To demonstrate the functionality and the …
… a ground structure from a flying object. The theses include both digital and analog electronics, which makes it a complex design task. The detector was constructed using analog circuits, from the signal processing of the incoming reflected pulse to the generation of a voltage …
… can show pulse and time difference between the signals. Both a digital and an analog approach for this purpose have been examined in the work. The result was that the analog solution worked better because the conversion could be performed with OP-amplifier instead of algorithms …
… med allt från marknadsundersökningar till lödning. Projektet innehåller såväl analog elektronik som programmering. Mycket tid gick åt till själva förarbetet, kanske lite väl mycket då det kändes som halva tiden gick åt innan jag kunde komma igång och arbeta. Jag lyckades få fram …
… of digital signals is today more frequently used than transmission of analog signals. One reason for this is that a digital signal is less sensitive to noise than an analog, another reason is that almost all signals today are handled in a digital format. This thesis describes …
… with a lower production cost. Our work has been divided into one part about analog signal conditioning and a second part with digital filtering and memory management of the sampled data. The analog part, designed of regular components like instrument amplifiers, voltage …
The thesis demonstrates a low-cost, low-bandwidth and low-resolution Analog-to- Digital Converter(ADC) in 0.35 um CMOS Process. A second-order Sigma-Delta modulator is used as the basis of the A/D Converter. A Semi-Uniform quantizer is used with the modulator to take advantage …
The report descripbs how a diplexer for a hybrid analog/digital filterbank has been constructed and tested. A diplexer divides the frequency band into two different bands that do not who doesn't overlapp each other. The sampling rate for the two ADC:s is 80 Msps, and therefore …
AnSyn AB är ett företag i Linköping som utvecklar programvara för att optimera analog elektronik. I deras program Analog Dimensions finns en visualiseringsmodul som ritar upp de kopplingsscheman som elektronikkonstruktören arbetar med. Ansyn var inte nöjda med den lösningen de …
… ideas through the use of a laboratory environment and has resulted in an analog design for laboratory purpose. A reconfigurable design is the result of this thesis as an alternative to the solution used today. In the proposed design mainly digital otentiometers, switches and …
… a voltage reference network for a 12-bit PSAADC, Parallell Successive Analog to Digital Converter. A chip containing the design has been sent away for fabrication. Because of the long processing time, no measurement data are presented. The main specifications for the voltage …
Då de flesta avståndsmätare idag använder sig av vanliga fotodioder har uppgiften varit att konstruera en mottagarenhet som använder sig av en lavinfotodiod. En lavinfotodiod kan registrera svagare signaler än en vanlig fotodiod och kan därför förbättra en avståndsmätares …
