The transistor continuously monitors V diff and adjusts its emitter voltage to equal V in minus the mostly constant V BE (approximately one diode forward voltage drop) by passing the collector current through the emitter resistor R E. As a result, the output voltage follows the input voltage variations from V BE up to V +; hence the name ...
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).

A typical example of the use of a common-emitter amplifier is shown in Figure 3. Figure 3: Single-ended npn common-emitter amplifier with emitter degeneration. The AC-coupled circuit acts as a level-shifter amplifier. Here, the base–emitter voltage drop is assumed to be 0.65 volts.
Emitter bias. When a split supply (dual power supply) is available, this biasing circuit is the most effective. It provides zero bias voltage at the emitter or collector for load. [clarification needed] The negative supply V ee is used to forward-bias the emitter junction through R e. The positive supply V cc is used to reverse-bias the ...

When the emitter Fermi level is used as the reference zero level, both ε and ε n can be either positive or negative. Energy analysis experiments have been made on field emitters since the 1930s. However, only in the late 1950s was it realized (by Young and Mueller [ 31 ] [,YM58]) that these experiments always measured the total energy ...

Simplified atomic structure of the NV center. The nitrogen-vacancy center (N-V center or NV center) is one of numerous photoluminescent point defects in diamond.Its most explored and useful properties include its spin-dependent photoluminescence (which enables measurement of the electronic spin state using optically detected magnetic resonance), and its relatively long (millisecond) spin ...
