Over-sampled digital-to-analog converters typically employ a unit-element architecture to drive out the analog signal. Performance can suffer from errors due to mismatch between unit elements, leading to a sharp drop in the achievable signal-to-noise ratio (SNR). Mismatch noise shaping is an established technique for overcoming these limitations, but(More)
Seawater desalination plants discharge brine which is at higher salt concentration than the supplied seawater feed. Diluting this brine by mixing it with the lower concentration feed (seawater) will reduce the environmental hazards associated with the high salt concentration of the disposed brine. Energy can be generated from the dilution process in which(More)
Quadrature bandpass delta-sigma data converters are widely used in low-IF receiver applications where high linearity is required over a narrow bandwidth. A quadrature delta-sigma modulator with multibit quantization requires a digital-to-analog converter (DAC) for each of the in-phase (I) and quadrature (Q) paths. Device mismatch errors in the DAC can(More)
this project is concerned with finding ways to synthesize hardware-efficient digital filter algorithms given technology and data-rate constraints. The synthesis flow targets embedded systems implemented in application specific integrated circuits (ASICs). The flexibility inherent in such custom implementations provides opportunities for optimization down to(More)
