The threshold current is typically 70mA and the forward voltage is a minimum 3 V to a maximum of 4V.
All predicted median current densities in ROIs, calculated using either isotropic or anisotropic models, exceeded threshold current densities reported to cause phosphenes [22].
The sensor capacity used to compute TPL is defined as the time required for the sensor to reach the threshold current, [[tau].sub.PMS].
A novel waveguide structure to reduce beam divergence and threshold current in GaInP/AlGaInP visible quantum-well lasers.
Up to 16 integrated PROFINET output interfaces with selective monitoring are available with the system and may be individually set for voltage and threshold current.
Within this context, the objectives of this study are (1) to evaluate and compare the action of the 50 mg/kg dose of RDP on the duration of cardiac action potentials (APs) at 30, 50, and 90% in normal and diabetic rats and (2) to analyse the functional organization of the ventricular syncytium through the input resistance versus threshold current curve of the hearts of control rats, control rats with RDP, diabetic rats, and diabetic rats with RDP administered daily for 90 days.
Here the sub threshold current is the main leakage component in CMOS devices when it is in the OFF state.
It offers a massive 700mW optical output power at a typical centre lasing wavelength of 638nm, has an operating temperature up to 40 degrees C, typical operating voltage of 2.2V, LD reverse voltage of 2V, with a typical threshold current of 200mA and operating current of 820mA.
Figure 2 plots such a variation, showing that LF-RIN increases with the increase in I around the threshold current [I.sub.th].
Consequently, it is important that the arrays have some parallel and some series connections in order to maintain current levels and to provide almost the same logic characteristics with a similar threshold current.
Rather than using pulse height data acquisition and analysis, the samples are evaluated only to determine if the PMTs are emitting a signal above a preset threshold current. Every sample over threshold means a single digit (logical 1) is sent to a high-speed field-programmable gate array (FPGA).
