This paper presents a new approach to capacitor placement in differential charge-scaling data converters. Good capacitor matching is crucial for charge-scaling converter resolution. Differential circuits are preferred to single-ended architectures due to improved immunity to noise and variations. The proposed method is based on the analysis of converter static nonlinearity equations. The impact of...
By combining Fractional Spectral Subtraction (FSS) with Perceptual Linear Predictive (PLP), a hybrid method of noise robustness speech recognition isinvestigated in this paper. This method uses FSS for noisy speech to reduce noise components in the fractional Fourier domain. According to the results ofcomputing Itakura distance and Mean Square Error (MSE), an approximate optimal fractional order is...
