DOI: 10.1109/jssc.2022.3166960
Abstract: This article introduces a new discrete-time (DT) charge-sharing (CS) low-pass filter (LPF) that achieves high-order filtering and improves its stopband rejection while maintaining a reasonable duty cycle of the main clock at 20%. It proposes… read more here.

DOI: 10.1134/s1995080219010062
Abstract: Bhatia, Lim, and Yamazaki conjectured that the Kubo–Ando extensions of means of numbers satisfy a norm minimality condition with respect to unitarily invariant norms. In this short note, we introduce a symmetric Kubo–Ando mean and… read more here.

DOI: 10.17863/cam.46117
Abstract: Typically we do not add objects in conformal geometric algebra (CGA), rather we apply operations that preserve grade, usually via rotors, such as rotation, translation, dilation, or via reflection and inversion. However, here we show… read more here.
