Spectral shaping of DAC nonlinearity errors through modulation of expected errors

Andersson, Ola,1976-Linköpings universitet,Elektroniksystem,Tekniska högskolan (author)

Traditionally, delta-sigma modulation has been used for shaping of quantization noise. We present a modified version of delta-sigma modulation which also takes into account unwanted nonlinearities by feeding back not only the quantization error, but also the expected physical error. Behavioral-level simulations of a 5th-order structure showing an improvement of up to 4 effective bits are included
