A High Speed Sigma Delta A/D-Converter for a General Purpose RF Front End in 90nm-Technology (EEE/ECE Project)
In this report a transistor-level design of a GHz Sigma-Delta analog-to-digital converter for an RF front end is proposed. The design is current driven, where the Continue reading
Design and Implementation of Comparator for Sigma Delta Modulator (Electronics Project)
Comparator is the main building block in an ADC architecture. Main purpose of the comparator is to compare a signal with a reference signal and produce an Continue reading
Space Vector Modulated – Direct Torque Controlled (DTC–SVM) Inverter – Fed Induction Motor Drive (Electrical/Electronics Project)
Introduction:
The Adjustable Speed Drives (ADS) are generally used in industry. In most drives AC motors are applied. The standard in those drives are Continue reading
Analog-to-Digital Converter Design for Non-Uniform Quantization (Electronics Project)
The study 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 Continue reading
Voice recorder using ADC and Microcontroller
Create a voice recorder using a PIC or a microcontroller and ADC. Use some conditioning circuits to condition the microphone output and feed it to the ADC. The converted values can be stored in some kind of memory. Samsung has some nice memory chips that can be easily interfaced. Most modern MP3 players use this kind of memory. Continue reading
