This work presents a four-quadrant current-mode CMOS multiplier structure based on the Advanced Compact MOSFET (ACM) Model. On the contrary of most traditional approaches for implementing CMOS multipliers, the proposed configuration is valid in the whole inversion regime of the MOS transistor, providing wide input range and improved linearity. The main theoretical principle of our multiplier li...

One of transient phenomenon that causes the mal-operation of the power transformer differential protection during the energization of a loaded power transformer is the ultra-saturation phenomenon. In this paper, a new model for investigating the ultra-saturation phenomenon during the energization of a loaded power transformer is presented and its effect on the differential protection of the pow...

A correlation between the gated-diode R-G current and the performance degradation of SOI n-channel MOS transistor after F-N stress test has been demonstrated in this paper. Due to increase of interface traps after F-N stress test, the generation-recombination (R-G) current of the gateddiode in the SOI-MOSFET architecture increases while the performance characteristics of MOSFET transistor such ...

An on-chip process, supply voltage, and temperature (PVT) compensation technique for low-voltage CMOS digital circuits was proposed. Because the degradation of circuit performance originates from the variation of the saturation current in transistors, we developed a compensation circuit consisting of a reference current that is independent of PVT variations. The circuit is operated so that the ...

The effects of environmental factors on variations of dissolved oxygen (DO) saturation was assessed in 2 estuaries (Bilbao and Urdaibai) in the Bay of Biscay with contrasting hydrography and anthropogenic impact, for the period 1997 to 2006, using generalised additive models (GAMs) and generalised additive mixed models (GAMMs). Spatial and temporal variations in DO saturation and the current se...

We tested whether the thecosome pteropod Limacina helicina from Puget Sound, an urbanized estuary in the northwest continental US, experiences shell dissolution and altered mortality rates when exposed to the high CO2, low aragonite saturation state (Ωa) conditions that occur in Puget Sound and the northeast Pacific Ocean. Five, week-long experiments were conducted in which we incubated pteropo...
