This paper offers a review of the literature on the theoretical and practical working of SAR ADC for 12-bit resolution and 40-50 MSPS in SCL 180nm technology. Data convertors are essential in any digital processing system. It is instrumental in acquiring sensor data in a meaningful way. In the process of circuit miniaturization, Successive Approximation Register (SAR) Analog-to-Digital Converter (ADC) with its simple structure, moderate speed and low power consumption, it is widely used in application fields such as mobile devices, wireless communication, smart sensors, medical imaging and industrial automation. Ground Penetrating Radar (GPR) systems require high-resolution, power-efficient Analog-to-Digital Converters (ADCs) capable of operating reliably in noisy and radiation-prone environments. This literature review examines recent advancements in Successive Approximation Register (SAR) ADCs, highlighting technologies and techniques that address challenges such as resolution accuracy under noise, power-speed-area trade-offs, and the demand for cost-effective, robust designs. Reference papers were studied, focusing on high-speed, low power architectures, comparator enhancements, DAC innovations, and layout-level implementations in SCL 180nm technology.
