Design of Pipelined Analog-to-Digital Converter with SI Technique in 65 nm CMOS Technology (Electronics Project)
Analog-to-digital converter (ADC) plays an important role in mixed signal processing systems. It serves as an interface between analog and digital signal processing systems. In the last two decades, circuits implemented in current-mode technique have drawn lots of Continue reading
Analysis and Design of High-Speed A/D Converters in SiGe Technology (Electronics Project)
Mixed-signal systems play a key role in modern communications and electronics. The quality of A/D and D/A conversions deeply affects what we Continue reading
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 of a parallel A/D converter system on PCB: For high-speed sampling and timing error correction (Electronics Project)
The goals for most of today’s receiver system are sampling at high-speed, with high resolution and with as few errors as possible. This project describes the design of a high-speed sampling system with”state-of-the-art”components available Continue reading
Design of a Voice Recorder using ADC Microcontroller
The C8051F411 offers a versatile, small (5 x 5 mm), highly integrated, low-power solution for voice applications. The 12-bit ADC and DAC allow for reasonable quality sound at a 8 kHz sampling rate, and the hardware Accumulation and Burst Mode features of the ADC provide for further improvements with small processing tradeoffs. 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
