The unscented transform (UT) is proposed as an alternative to the Monte Carlo (MC) method for assessing performance variability of electronic circuits based on emergent technologies. We show that the discrete UT approximation of a continuous probabil

This paper presents a nonlinear quantization technique applied in a multibit sigma-delta $\Sigma\triangle$ modulator. The technique is based on the unscented transform and utilizes a flash topology to modeling the quantizer of the modulator. To verif

Advancements on analog integrated design have led to new possibilities for complex systems combining both continuous and discrete time modules on a signal processing chain. However, this also increases the complexity any design flow needs to address

This paper presents an analog-to-digital converter with a novel adaptive wavelet-based sampling scheme. The proposed algorithm uses the wavelet transform to localize critical points in the signal, while the estimated Lipschitz exponent describes the

This paper presents a novel approach to the design of signal specific quantizers based on the Unscented Transform. This is done in such a way that we preserve the statistical moments of the input signal on the quantization process. We define the desi
