Analog-to-Digital Converters (ADCs) are crucial components in various electronic systems, responsible for converting continuous analog signals into discrete digital signals that can be processed by digital circuits. A fundamental building block of these ADCs is the bit analog to digital converter input, which plays a pivotal role in initiating the conversion process. The ADC input generally consists of an amplifier and a quantizer. The amplifier enhances the resolution of the input signal, ensuring it reaches sufficient amplitude for accurate digitization. Subsequently, the quantizer partitions the output into discrete levels or bits, effectively discretizing the analog signal.
