Review of Different Types of Power Efficient Flash Type ADC

Ashish Kumar ^[25] | Deepak Mehra ^[2]

Abstract: This review paper inherits few different types of architecture for a low-power high speed Flash Analog-to-Digital Converter (ADC). Unlike conventional Full-Flash architecture in which power consumption is increased exponentially with the increase of resolution. New techniques adopted at the design level, such as the TIQ (Threshold Inverter Quantizer) structure and multiplexer in order to make the physical circuit very compact. In contrast with the traditional Flash ADC architecture that uses an area inefficient resistive ladder, 2-1 comparator, and an encoder, these design makes use of only a series of inverters and multiplexers. As a result, minimum power consumption would be achieved.
