  2. Diode–transistor logic - Wikipedia

    en.wikipedia.org/wiki/Diodetransistor_logic

    Diodetransistor logic (DTL) is a class of digital circuits that is the direct ancestor of transistortransistor logic. It is called so because the logic gating functions AND and OR are performed by diode logic , while logical inversion (NOT) and amplification (providing signal restoration) is performed by a transistor (in contrast with ...

  3. Diode logic - Wikipedia

    en.wikipedia.org/wiki/Diode_logic

    If a diodetransistor logic gate drives a transistor inverter of similar construction, the transistor will have a similar base-collector capacitance that is amplified by the transistor gain, so that it will be too slow to pass the glitch. But when the diode is much slower, recovery will become a concern:

  4. Transient-voltage-suppression diode - Wikipedia

    en.wikipedia.org/wiki/Transient-voltage...

    A transient-voltage-suppression diode can respond to over-voltages faster than other common over-voltage protection components such as varistors or gas discharge tubes. The actual clamping occurs in roughly one picosecond , but in a practical circuit the inductance of the wires leading to the device imposes a higher limit.

  5. Load line (electronics) - Wikipedia

    en.wikipedia.org/wiki/Load_line_(electronics)

    The intersections of the load line with the transistor characteristic curves represent the circuit-constrained values of I C and V CE at different base currents. [2] If the transistor could pass all the current available, with no voltage dropped across it, the collector current would be the supply voltage V CC over R L. This is the point where ...

  6. Logic family - Wikipedia

    en.wikipedia.org/wiki/Logic_family

    Diodetransistor logic (DTL) was used in the IBM 608 which was the first all-transistorized computer. Early transistorized computers were implemented using discrete transistors, resistors, diodes and capacitors. The first diodetransistor logic family of integrated circuits was introduced by Signetics in 1962.

  7. Shockley diode equation - Wikipedia

    en.wikipedia.org/wiki/Shockley_diode_equation

    As for the second, the difference between the quasi-Fermi levels at the junction, he says that we can estimate the current flowing through the diode from this difference. He points out that the current at the p terminal is all holes, whereas at the n terminal it is all electrons, and the sum of these two is the constant total current.

  8. Snubber - Wikipedia

    en.wikipedia.org/wiki/Snubber

    The diode is installed so that it does not conduct under normal conditions. When the external driving current is interrupted, the inductor current flows instead through the diode. The stored energy of the inductor is then gradually dissipated by the diode voltage drop and the resistance of the inductor itself. One disadvantage of using a simple ...

  9. Diode-connected transistor - Wikipedia

    en.wikipedia.org/wiki/Diode-connected_transistor

    A diode-connected transistor is a method of creating a two-terminal rectifying device (a diode) out of a three-terminal transistor. A characteristic of diode-connected transistors is that they are always in the saturation region for metal–oxide–semiconductor field-effect transistors (MOSFETs) and junction-gate field-effect transistors ...
