Transistor in a sentence

A mnemonic device for the PNP transistor symbol is "pointing in (proudly/permanently)", based on the arrows in the symbol and the letters in the name. citation Heterojunction bipolar transistor Bands in graded heterojunction NPN bipolar transistor.

Transistor organs Hammond started making transistor organs by the mid-1970s In the 1960s, Hammond started making transistor organs.

Transistor packages are mainly standardized, but the assignment of a transistor's functions to the terminals is not: other transistor types can assign other functions to the package's terminals.

Active-mode PNP transistors in circuits Structure and use of PNP transistor The diagram shows a schematic representation of a PNP transistor connected to two voltage sources.

Although they did not contain any microprocessors, but were built around transistor-transistor logic (TTL), Hewlett-Packard calculators as far back as 1968 had various levels of programmability such that could be called microcomputers.

An NPN transistor comprises two semiconductor junctions that share a thin p-doped anode region, and a PNP transistor comprises two semiconductor junctions that share a thin n-doped cathode region.

A plot of CPU transistor counts against dates of introduction; note the logarithmic vertical scale ; the line corresponds to exponential growth with transistor count doubling every two years.

During the transition the input transistor is briefly in its active region; so it draws a large current away from the base of the output transistor and thus quickly discharges its base.

It appears in contexts where the transistor is used as a temperature sensing device, e.g. the thermal "diode" transistor that is embedded within a computer's microprocessor.

It is called transistor–transistor logic because both the logic gating function (e.

Shockley intended to replace the current transistor with a new three-element design (today known as the Shockley diode ), but the design was considerably more difficult to build than the "simple" transistor.

The bipolar junction transistor (BJT) has traditionally been the analog designer's transistor of choice, due largely to its higher transconductance and its lower output impedance (drain-voltage independence) in the switching region.

The first implementation was the TS1, a central processing unit built from discrete transistor-transistor logic ( 74F TTL ) devices.

The new "SuperPLA", as it was dubbed, integrated many discrete components and transistor–transistor logic (TTL) chips.

The techniques developed during this program were equally useful for improving all transistor construction, and greatly reduced the failure rate of transistor production lines in general.

They are activated by AC control signals or DC control signals from Programmable logic controller (PLCs), PCs, Transistor-transistor logic (TTL) sources, or other microprocessor and microcontroller controls.

This requires two transistors for each pixel instead of the single transistor needed for a standard thin-film transistor (TFT) display.

Transistor amplifiers seeAlso Transistor amplifiers (or solid state amplifiers) are the most common type of amplifier in use today.

Transistor–transistor logic (TTL) was a great improvement over these.

Usage of bipolar and field-effect transistors The bipolar junction transistor (BJT) was the most commonly used transistor in the 1960s and 70s.
