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

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

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 … Read more »

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 … Read more »
