Can bjt used in adc
WebBJT can handle a lot more current than MOSFETs. One of the reason why they are still in use is BiCMOS applications where basically CMOS part is used as the logic and BJTs are used to drive very high capacitance nodes. Other than that, they have very nice properties regarding their PN junction nature. WebDec 8, 2016 · The magnitude of this leakage current is small – on the order of picoamps (pA). Since the inputs of bipolar junction transistor (BJT) amplifiers require base currents …
