Analog-Digital (A/D) converters used in instrumentation and measurements often require high absolute accuracy, including very high linearity and negligible dc offset. The realization of high-resolution Nyquist-rate converters becomes very expensive when the resolution exceeds 16 bits. The conventional delta-sigma (/spl Delta//spl Sigma/) structures used in telecommunication and audio applications usually cannot satisfy the requirements of high absolute accuracy and very small offset. The…
