A Low-Offset Low-Noise Sigma-Delta Modulator with Pseudorandom Chopper-Stabilization Technique
This paper presents a low-offset low-noise sigma-delta modulator with pseudorandom chopper-stabilization technique. The comparison of the noise-cancellation ability with the correlated double sampling and chopper-stabilization techniques is demonstrated;

Advanced Engineering Materials, EarlyView.A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.
