Abstract

Much research has been done in characterizing error mechanisms and compensating Analog to Digital Converters (ADCs). The process of calibrating the ADCs which evolved from this previous research has generally involved exciting the ADC with as many as 100 different single-tone signals. This paper explores the process and results of calibrating an ADC with as few as two wideband signals. Models of dynamic errors are developed using a harmonic based non-iterative approach. Hardware results show error models capable of compensating the ADC over the full Nyquist band. Simulation results confirm the validity of the algorithm
