WebA 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, uses only one kind of charge … WebThe phototransistor presented utilizes the present ability to dope QD layers to build junctions analogous to BJT devices. It is therefore able to provide a significant current gain through an emitter-base junction, as opposed to other devices which have thus far been limited to ambipolar field effect transistors.
WebPhototransistor amplifies the base current into its collector current. Since base current depends on the light intensity, the collector current varies with the intensity of light. They are used for sensing light pulses of high speed … Webspeed of the phototransistor is clearly demonstrated. The top trace is the input current while the two bottom traces depict the CE and CC output waveforms respectively.
