Abstract

Most of the signals available in nature are analog. Since sensor operates in analog domain, data converters play an important role in transformation of these signals to digital form or vice versa in real-world applications. Various techniques are used to develop analog-to-digital converters (ADC) and these are designed in trade-off of power, speed and area. Few of the techniques are Flash type, successive approximation, sigma-delta, counter type ADC, dual-slope ADC, etc. Each type has its own advantages and limitations. For high-speed applications, Flash ADC is considered to be best candidate. Optimized comparator and decoder designs can contribute in reduction of power consumption. Since electronic devices are becoming portable, Flash ADCs are integrated with SoC configuration. Linear operation, overall size reduction and improved performance are expected features of the design to achieve the same.
