Negative-bias temperature instability (NBTI) is a key reliability issue in MOSFETs, a type of transistor aging.NBTI manifests as an increase in the threshold voltage and consequent decrease in drain current and transconductance of a MOSFET.
Crystal structure of β-glucosidase from Thermotoga neapolitana (PDB: 5IDI).Thermostable protein, active at 80°C and with unfolding temperature of 101°C. [1]In materials science and molecular biology, thermostability is the ability of a substance to resist irreversible change in its chemical or physical structure, often by resisting decomposition or polymerization, at a high relative ...
thermal triggering; light triggering; Forward-voltage triggering occurs when the anode–cathode forward voltage is increased with the gate circuit opened. This is known as avalanche breakdown, during which junction J2 will break down. At sufficient voltages, the thyristor changes to its on state with low voltage drop and large forward current.
Chemical reactions involving thermal runaway are also called thermal explosions in chemical engineering, or runaway reactions in organic chemistry.It is a process by which an exothermic reaction goes out of control: the reaction rate increases due to an increase in temperature, causing a further increase in temperature and hence a further rapid increase in the reaction rate.
Junction temperature, short for transistor junction temperature, [1] is the highest operating temperature of the actual semiconductor in an electronic device. In operation, it is higher than case temperature and the temperature of the part's exterior.
For small-signal transistors (e.g., not power transistors) with relatively high values of β (i.e., between 100 and 200), this configuration will be prone to thermal runaway. In particular, the stability factor, which is a measure of the change in collector current with changes in reverse saturation current, is approximately β
[17] [3] In a "diamond buffer Triple" configuration the added transistors form a conventional emitter follower. [3] The drawback is that the circuit requires its own bias spreader for thermal regulation. [3] Emitter resistors in the output stage are not necessary for thermal stability, but are critical for minimizing crossover distortion.
In thermodynamics, thermal stability describes the stability of a water body and its resistance to mixing. [1] It is the amount of work needed to transform the water to a uniform water density . The Schmidt stability "S" is commonly measured in joules per square meter (J/m 2 ).
