where J is the emission current density, T is the temperature of the metal, W is the work function of the metal, k is the Boltzmann constant, q e is the Elementary charge, ε 0 is the vacuum permittivity, and A G is the product of a universal constant A 0 multiplied by a material-specific correction factor λ R which is typically of order 0.5.
The slew rate (SR) of a simple diamond buffer is limited by I e1 at SR=I e1 /C int1, where the internal capacitance C int1 is the total capacitance "seen" by the current source I e1 at the common node of the base of T2 and the emitter of T1 (or, in case of I e2, at the common node of the base of T4 and the emitter of T3). [25] For example, a 0. ...

In electronics, emitter-coupled logic (ECL) is a high-speed integrated circuit bipolar transistor logic family. ECL uses an overdriven bipolar junction transistor (BJT) differential amplifier with single-ended input and limited emitter current to avoid the saturated (fully on) region of operation and the resulting slow turn-off behavior.

Qualifying households must have a gross annual income at or below 175% of the federal poverty level. For a family of four, that is $54,600. ... it’s not just about the utilities, it’s also ...
Figure 2: Adding an emitter resistor decreases gain, but increases linearity and stability. Common-emitter amplifiers give the amplifier an inverted output and can have a very high gain that may vary widely from one transistor to the next. The gain is a strong function of both temperature and bias current, and so the actual gain is somewhat ...
