The use of Delta-Sigma modulation in fully digital transmitter architectures has emerged as a versatile means of achieving high spectral purity and wideband agility without reliance on analogue mixers ...

Delta-sigma modulation is a cornerstone approach for high-resolution analogue-to-digital conversion, combining oversampling with active noise shaping to achieve superior signal fidelity. In these ...

Where digital and analog designs are overlapping, and why it’s becoming more difficult to ensure they work as expected over their lifetimes. Pujol: We need some abstraction because we cannot ...
