The proceedings contain 59 papers. The topics discussed include: an architecture for a reconfigurable charge-summation based AdC;strategic AdC design evaluation based on error sources;novel digital pre-correction method for mismatch in dACS with built-in self-measurement;a closed loop precision dAC;a closed loop precision dAC;behavior of AdC nonlinearities in multichannel antenna array digitizer systems;multiband analog to digital conversion;low-power, high-speed, AdC/dAC design for satellite communications;parallel-path d/a convertors for near-Nyquist signal generation;and recent advances in multi-bit continuous-time band-pass delta-sigma modulator.
This paper outlines the design of an architecture that uses multiple AdCs in parallel to quantize several different bands of a wideband signal. A multirate filter bank is applied to reconstruct the wideband signal fro...

It is a striking fact that high accuracy industrial dACs lag behind AdCs, in terms of resolution, monotonicity, offset and other measures of 'dc' precision. Some of the reasons for the better dc performance of...

In this paper, least square error (LSE) techniques are used to derive the most common figures of merit of analog-to-digital converters from one quick single-tone measurement. Using the fitting techniques, the causes o...
