"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 for proper bias, however, the BJT input bias current is a lot larger – on the order of microamps (µA). Hence, input bias current is an important issue for BJT amplifiers. " - Bjt leakage current
