Abuelma’atti, M.T. (1993) Effect of bit-threshold errors on the harmonic and intermodulationperformance of successive approximation A/D converters. Communications, IEEE Transactions on, 41.
A simple approach is described for predicting the harmonic and intermodulation performance of a real successive approximation analog-to-digital converter (ADC) with bit-threshold errors. The real ADC characteristic is split into an ideal staircase characteristic, representing the ideal ADC characteristic, minus a train of pulses, representing the bit-threshold errors. Series expressions are obtained for the output spectra of the real ADC excited by a multicarrier input signal with arbitrary amplitudes. The special case of two equal-amplitude carriers is considered in detail, and analytical expressions are obtained for the amplitudes of the harmonic and intermodulation products in terms of the individual bit-threshold errors. The feasibility of minimizing the amplitudes of the intermodulation products is explored
