Impact of random channel mismatch on the SNR and SFDR of time-interleaved ADCs
(Institute of Electrical and Electronics Engineers, 2004)
Using several ADCs (Analog to Digital Converters) in parallel with convenient time offsets is considered as an efficient way to push the speed limits of data acquisition systems. However, a serious drawback of this ...

Cascade ΣΔ modulator with digital correction for finite amplifier gain effects
(Institute of Electrical and Electronics Engineers, 2004)
This paper presents a simple and fully digital solution to correct the effect of amplifier finite gain in cascade ΣΔ modulators. The main contribution of this letter is a simple digital method to evaluate the integrator ...

Low-voltage CMOS log-companding techniques for audio applications
(Springer, 2004)
This paper presents a collection of novel current-mode circuit techniques for the integration of very low-voltage (down to 1 V) low-power (few hundreds of μA) complete SoCs in CMOS technologies. The new design proposal is ...

Digital test for the extraction of integrator leakage in first- and second-order ΣΔ modulators
(Institute of Electrical and Electronics Engineers, 2004)
This paper proposes a digital technique to evaluate the integrator leakage within 1st and 2nd order ΣΔ modulators. Integrator leakage is known to be related to the converter precision and belongs to the basic set of design ...
