Abstract
An analog digital converter that does not require a dedicated reference voltage, can digitize a rail-rail input signal and provide house-keeping functions to a ROIC or other IC. The RHADR system may operate without support from a main electronics board, which would only have to supply a power supply voltage to, and read the outputs from, the chip. This is achieved with (1) a Pivoting Successive Approximation Register ADC (PSAR ADC) and (2) radiation hard by design (RHBD) techniques.
