Positive emitter-coupled logic — Positive emitter coupled logic, or PECL, is a further development of the emitter coupled logic (ECL) technology and requires a positive 5V supply instead of a negative 5V supply. The Low voltage positive emitter coupled logic (LVPECL) is an… … Wikipedia
Voltage-gated ion channel — Voltage gated ion channels are a class of transmembrane ion channels that are activated by changes in electrical potential difference near the channel; these types of ion channels are especially critical in neurons, but are common in many types… … Wikipedia
Positive feedback — Alarm or panic can spread by positive feedback among a herd of animals to cause a stampede. Positive feedback is energy taken from the output of a system and reapplied to the input, which is phase congruent with the input signal. A system… … Wikipedia
Voltage multiplier — Villard cascade voltage multiplier. A voltage multiplier is an electrical circuit that converts AC electrical power from a lower voltage to a higher DC voltage, typically by means of a network of capacitors and diodes. Voltage multipliers can be… … Wikipedia
Positive Logik — Digitalsignal (binär) In der Digitaltechnik bezeichnen Logikpegel definierte Bereiche für elektrische Spannungen, die sich auf Masse (Ground, GND) beziehen. Bei den üblichen binären Signalen sind zwei Spannungsbereiche erlaubt, die High Pegel… … Deutsch Wikipedia
Voltage doubler — A voltage doubler is an electronic circuit which charges capacitors from the input voltage and switches these charges in such a way that, in the ideal case, exactly twice the voltage is produced at the output as at its input. The simplest of… … Wikipedia
