Published in 2021 at "Analog Integrated Circuits and Signal Processing"

DOI: 10.1007/s10470-021-01899-8

Abstract: An efficient architecture of a high-performance ultra-low-voltage gate-driven two-stage pseudo-fully differential operational transconductance amplifier (OTA) is presented. The proposed subthreshold-region operated OTA utilizes two identical conventional current-mirror-based source coupled pseudo-differential amplifiers with their cross-connected gate… read more here.

Abstract: Let $$s\ge 1$$s≥1, $$\omega ,\omega _0\in {\mathscr {P}}_{E,s}^0$$ω,ω0∈PE,s0, $$a\in \Gamma _{s}^{(\omega _0)}$$a∈Γs(ω0), and let $${\mathscr {B}}$$B be a suitable invariant quasi-Banach function space. Then we prove that the pseudo-differential operator $${\text {Op}}(a)$$Op(a) is continuous from… read more here.

Published in 2017 at "Integral Transforms and Special Functions"

DOI: 10.1080/10652469.2017.1288726

Abstract: ABSTRACT A pair of pseudo-differential operators (p.d.o.) involving the Kontorovich–Lebedev transform (KL-transform) as well as its adjoint is defined. Estimates for translation and convolution function associated with the Kontorovich–Lebedev transform are obtained. Continuity of KL-transform… read more here.

Published in 2023 at "Asian-European Journal of Mathematics"

DOI: 10.1142/s1793557123501449

Abstract: In this paper, the study of linear canonical Hankel pseudo-differential operators has been extended to Sobolev-type spaces. Two versions of pseudo-differential operators involving linear canonical Hankel transformation are defined. We have shown that the pseudo-differential… read more here.
