[1] [2] Both circuits drawn to underscore the bridged topology of push-pull operation The diamond buffer or diamond follower is a four-transistor, two-stage, push-pull , translinear emitter follower , or less commonly source follower , in which the input transistors are folded, or placed upside-down with respect to the output transistors.

Electrothermal-chemical (ETC) technology is an attempt to increase accuracy and muzzle energy of future tank, artillery, and close-in weapon system [1] guns by improving the predictability and rate of expansion of propellants inside the barrel.
In electron emission devices, especially electron guns, the thermionic electron emitter will be biased negative relative to its surroundings. This creates an electric field of magnitude E at the emitter surface. Without the field, the surface barrier seen by an escaping Fermi-level electron has height W equal to the

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 ...
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 ...
The Ohio Department of Development and The Breathing Association want to help alleviate the burden of costly energy bills this winter and keep more of Ohio’s families warm through March 31.
The Philadelphia 76ers have been off to a rough start this season, falling to 2-11 after a loss to the Miami Heat on Monday. And things in the locker room are reportedly a bit shaky as well, with ...
