Current differencing transconductance amplifiers (CDTAs) provide a versatile platform for signal processing in contemporary integrated circuits. By converting differential input currents into ...

This paper introduces a novel current differencing circuit based on a flipped voltage follower (FVF) architecture. The design incorporates an FVF-based current mirror to achieve wide-range current ...

The presence of a unit root indicates that the time series is not stationary but that differencing will reduce it to stationarity. The tests proposed to data require specification of the number of ...
