A Different View of Sigma-Delta Modulators Under the Lens of Pulse Frequency Modulation
Victor Medina, Pieter Rombouts, Luis Hernandez
The fact that VCO-ADCs produce noise-shaped quantization noise suggests that a link between frequency modulation and Sigma-Delta modulation should exist. The connection between a V…

A Second-Order Audio VCO-ADC with 103-dB-A Dynamic Range and Binary-Weighted Internal Architecture
Victor Medina, Ruben Garvi, Javier Granizo +2
One of the limitations of conventional VCO-ADCs is the restriction to first-order noise shaping. True-VCO architectures have been proposed to increase the noise-shaping order by ca…
