New tests for checking asymptotic stability of positive 1D continuous-time and discrete-time linear systems without and with delays and of positive 2D linear systems described by the general and the Roesser models are proposed. Checking of the asymptotic stab…
Chin-Hsin Lin, Marek Syrzycki
This paperpresents a single-stage Vernier Time-to-Digital Converter (VTDC) that utilizes the dynamic-logic phase detector. The zero dead-zone characteristic of this phase detector allows for the single-stage VTDC to deliver sub-gate delay time resolution. The…
