There are two types of transistors, with slight differences in how they are used: A bipolar junction transistor (BJT) has terminals labeled base , collector and emitter . A small current at the base terminal, flowing between the base and the emitter, can control or switch a much larger current between the collector and emitter.
The transistor count is the number of transistors in an electronic device (typically on a single substrate or silicon die).It is the most common measure of integrated circuit complexity (although the majority of transistors in modern microprocessors are contained in cache memories, which consist mostly of the same memory cell circuits replicated many times).
In 2020, it was still the dominant transistor type in use, with an estimated total of 13 sextillion (1.3 × 10 22) MOSFETs manufactured between 1960 and 2018. The key advantages of a MOSFET transistors over BJTs are that they consume no current except when switching states and they have faster switching speed (ideal for digital signals).
A matchstick is pictured for scale. In electronics, the metal–oxide–semiconductor field-effect transistor (MOSFET, MOS-FET, MOS FET, or MOS transistor) is a type of field-effect transistor (FET), most commonly fabricated by the controlled oxidation of silicon.
The connection of n-type and p-type semiconductors form p–n junctions. The most common semiconductor device in the world is the MOSFET (metal–oxide–semiconductor field-effect transistor), [1] also called the MOS transistor. As of 2013, billions of MOS transistors are manufactured every day. [2]
BJTs PNP and NPN schematic symbols. 3D model of a TO-92 package, commonly used for small bipolar transistors. A bipolar junction transistor (BJT) is a type of transistor that uses both electrons and electron holes as charge carriers. In contrast, a unipolar transistor, such as a field-effect transistor (FET), uses only one kind of charge carrier.
There are several logic families with different characteristics (power consumption, speed, cost, size) such as: RDL (resistor–diode logic), RTL (resistor-transistor logic), DTL (diode–transistor logic), TTL (transistor–transistor logic) and CMOS. There are also sub-variants, e.g. standard CMOS logic vs. advanced types using still CMOS ...
