The world around the users is analog in nature i.e. all changes and physical phenomenon occurring are continuous. However, due to the various advantages of having data in digital format like storage, processing, transmission, etc., the authors prefer to convert these continuous varying quantities into discreet digital values. This process in known as quantization and the device employed for quantization is known as an Analog-to-Digital Converter (ADC). High speed low power ADCs are the critical building blocks for modem communication and signal processing systems.
