High false-negative rates of the Papanicolauo (so-called 'Pap') smear test and the shortage of colposcopists have led to the desire to find alternative non-expert (automated) approaches for accurately testing cervical smears for signs of cancer. Fourier-Transform Infra-Red (FTIR) spectroscopy has been shown to offer the potential for improving the accuracy(More)

In this paper we propose a robust correction scheme to tackle the well known problem of analog mismatch errors encountered in cascaded sigma delta modulators. The problem is cast in an H-infinity setting and solved using standard robust control tools. Guaranteed worst case performance is obtained and implementation overhead is minimised. The approach is(More)
