A REVIEW OF LOW POWER FLASH ADC USING THRESHOLD INVERTER QUANTIZATION TECHNIQUE
Journal Title: World Journal of Engineering Research and Technology - Year 2017, Vol 3, Issue 3
Abstract
Digital signal processing algorithms were becoming increasingly more powerful while advances in integrated circuit technology provided compact, efficient implementation of these algorithms in silicon. In the design of mixed-signal and system on chip (SOC) applications the analog-to-digital converter (ADC), is a key functional block which limits the performance and the speed of the system. The analog-to-digital converter is one of the most important component of signal processing and communication systems. An Analog to digital converter is a circuit that converts an analog signal such as a sound picked up by a microphone or light entering a digital camera, into digital signal. There are different types of ADCs depending on type of applications. There are three main categories of ADCs depending on the speed of operation i.e. low speed serial ADC, medium speed ADC and high speed ADC. The different types of ADCs based on various topologies are: Flash ADC, Sigma delta ADC, Ramp counter ADC, Successive approximation ADC. The flash ADC is known for having the fastest speed compared to other ADC architectures. Therefore, it is used for high-speed and very large bandwidth applications such as radar processing, digital oscilloscopes, high-density disk drives, and so on. This paper presents review of Low Power Flash ADC using Threshold inverter quantization technique.
