what is Hybrid Analog-to-Digital Converter？

A Hybrid Analog-to-Digital Converter (ADC) is a type of ADC that combines both analog and digital components to convert an analog signal into a digital representation. It typically consists of an analog front-end that amplifies and filters the analog input signal, followed by a digital back-end that performs the conversion and processing of the signal.

The analog front-end of a hybrid ADC includes components such as amplifiers, filters, and sample-and-hold circuits, which condition the analog input signal before it is fed into the digital back-end. The digital back-end consists of a digital converter, which converts the conditioned analog signal into a digital representation using techniques such as successive approximation, delta-sigma modulation, or flash conversion.

The hybrid ADC combines the advantages of both analog and digital components. The analog front-end can handle high-frequency signals and provide high dynamic range and linearity, while the digital back-end offers precise conversion and processing capabilities. This allows for accurate and efficient conversion of analog signals into digital data, which can be further processed and analyzed by digital systems
