ADC ARCHITECTURES
INTRODUCTION
An analog-to-digital converter is a device that converts a continuous quantity to a discrete.
High speed and resolution data converters.
Manufacturers have shown robust developments in the architectures of ADC’s and DAC’S. These developments have been characterized and studied in as FLASH ADC, INTEGRATED ADC, and PIPELINING ADC, etc.
TYPES OF ADC'S
FLASH ADC.
PIPELINE ADC.
INTEGRATING ADC.
SUCCESSIVE APPROXIMATION ADC.
RAMP-COMPARE ADC.
SIGMA-DELTA ADC.
APPLICATIONS
Applied to music recording.
Digital Signal Processing.
Very fast ADCs are needed in digital oscilloscopes, and are crucial for new applications like software defined radio.
