i need to store real time values of an circuit output which varies from 5v to 24 v in a micro controller 8051 but my prob is as micro controller takes only digital values i need to use an ADC to convert but the limitation of ADC s 5v what can i do to capture the real time values. ....etc

DAC and ADC converters

-Data Converter impacts the factor for the performance of the overall radio design
-Requirements: very high sampling rates, high number of effective quantization bits, an operating bandwidth of several Ghz, a large spurious-free dynamic range, a reasonable price
-DAC and ADC converters
-Sampling and Quantization
-Nyquist Zones
-Aliasing
-Bandpass filtering – uses image to translate bandpass signals to baseband
-Errors occurs in Quantization
-Quantization Noise

Abstract—

This paper proposes a new soft-switched continuousconduction- mode (CCM) boost converter suitable for high-power applications such as power factor correction, hybrid electric vehicles, and fuel cell power conversion systems. The proposed converter achieves zero-voltage-switched (ZVS) turn-on of active switches in CCM and zero-current-switched turn-off of diodes leading to negligible reverse-recovery loss. The components’ voltage ratings and energy volumes of passive components of the proposed converter are greatly reduce ....etc

MONOLITHIC LOW-POWER 16 B 1 SAMPLE/S SELF-CALIBRATING PIPELINE ADC

Abstract:- Pipelined architectures enable the implementation of high-speed, high-resolution, low-power analog-to-digital converters (ADCs). Concurrent processing of analog signals results in power and/or speed advantages over flash and multi step ADC architectures. While self-calibration techniques reduce the effects of component mismatches, the digital crosstalk due to correction circuitry can degrade the noise and linearity performance of the overall converter. Previous pip ....etc

A High Input Voltage Three-Phase ZVZCS DC-DC Converter with Vin /3 Voltage Stress on Primary Switches
Abstract
A high-voltage three-phase ZVZCS dc-dc converterwith low voltage stress is presented in this paper. The voltagestress on the primary switches is only one-third of the inputvoltage. By using the phase shift pulsewidth modulation (PWM)and secondary snubber, four of the six primary switches areoperating with zero-voltage switching (ZVS) and two of them areoperating with zero-current switching (ZCS), in order to reducethe switch ....etc

ABSTRACT

A pipelined analog-to-digital converter (ADC) architecture suitable for high-speed (150 MHz), Nyquist-rate A/D conversion is presented. At the input of the converter, two parallel track-and-hold circuits are used to separately drive the sub-ADC of a 2.8-b first pipeline stage and the input to two time-interleaved residue generation paths. Beyond the first pipeline stage, each residue path includes a cascade of two 1.5-b pipeline stages followed by a 4-b backend folding ADC. The full-scale residue range at the output of the pipeline ....etc
