A bipolar junction transistor (BJT) may be used in a power stage DC-to-DC converter, such as a converter in LED-based light bulbs. The power stage may be operated by a controller to maintain a desired current output to the LED load. A resistor may be coupled to the BJT through a ...
constantand the transistor breakdown characteristics. Depending on the LED you use, you may need to add a current limiting resistor to protect the LED during discharge. But for a typical 5mm white LED, no resistor is needed as the duration of the current flow is extremely short. Using the R...
Transistors are mainly divided into two categories: bipolar transistors (BJT) and field-effect transistors (FET). The transistor has three poles; the three poles of the bipolar transistor are composed of N-type and P-type emitters, bases and collectors; the three poles of the field-effect ...
A transistor is a three-terminal semiconductor device. Mostly it is used as a switching device and also as an amplifier. This switching device can be voltage or current controlled. By controlling the voltage applied to the one terminal controls the current flow through the other two terminals. ...

In summary, the BJT device is demonstrated to be a superior transducer in comparison to a FET in an electrochemical sensor. The application of field effect transistors (FET) as transducers in electrochemical sensors was first described in 1970 by Bergveld1. Since then, field effect transistor (...
The proposed HGJLT reduces the subthreshold leakage current and suppresses the parasitic BJT action in off-state by reducing the band-to-band tunnelling probability. 展开 关键词: hetero-gate-dielectric double gate junctionless transistor band-to-band tunnelling off-state ...
