Abstract: ABSTRACT A SYSTEM AND METHOD FOR PRECISE CALIBRATION OF 16 BIT ANALOG TO DIGITAL CONVERTER (ADC) The present invention provides a novel system and method with passive resistor and switch-based network designed to generate precise voltages ranging from -Vrange to +Vrange with the finest resolution, specifically configured for the calibration of a 16-bit Analog-to-Digital Converter (ADC). This system configuration allows the ADC to be tested for all integer multiples of the smallest resolution step within the full voltage range, ensuring highly accurate and reliable calibration. By generating the full spectrum of these voltages, the system guarantees that the ADC performs accurately across its entire input range, from the negative to the positive extreme, which is critical for applications requiring precise measurement. In the system, the switches are arranged in three rows, each configured in a specific pattern to form a complex resistive network. This configuration enables the generation of a wide range of pr
