… thesis, a direct-conversion receiver front-end has been designed in a 0.18um CMOS technology. Direct-conversion receivers (DCR) have obvious advantages over the heterodyne counterpart. Since the intermediate frequency (IF) is zero, the problem of image is circumvented. As a …
… 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 of input distributions that are …
The aim and goal of this work has been to design and implement 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 …
… is performed. The most suited is later implemented and simulated using the CMOS process AMS.C035. The component is also tested in a continuous-time elliptic low-pass filter of leapfrog type. The filter does not behave as it should. However, better performance can be obtained by …
A feasibility study
… architecture is current feedback amplifiers. A current feedback amplifier in CMOS with the required high voltages and slew rate is hard to realize without very high power consumption.
… language VHDL. The SRAM-memory that will be tested is build in CMOS-teknologi. The memorycells will be loaded with a predecided bitpattern. Changes in the memorycells will be registrated together with the adress where the fault came up. The equipment will be used of AT at the …
Sensor för att identifiera objekt på bilden från en videokamera
… Sensorn består av en mikroprocessor som programmeras i assembler samt en enkel CMOS-videokamera och tillhörande analag elektronik. Sensorn är främst tänkt att användas för övervakning inom tillverkningsindustrin.
Detta dokument beskriver hur man kan använda kameramodulen TRDB DC2 från Terasic tillsammans med ett utvecklingskort DE2 för Alteras FPGA-kretsar. Kamerabilder överförs från kameramodulen till en VGA-skärm. VGA-bilden har en upplösning på 640 x 480 pixlar och 10bitars upplösning …
… it could develop a material that can be resistant to radiation or like CMOS technology has proposed, to reduce the component to avoid the storage of charge in the oxide. Another solution can be the GRAPHENE. Its features will revolutionize the electronics and provide answer to …
