Web31 de jan. de 2016 · 483. The very high impedance is caused by the isolation layer between gate and channel. For the case of a MOSFET it is made of SiO 2 (resistance 10 16 Ω m). So, because of this, applying a voltage to the gate gives a small current - leakage current. If you compare to a normal bipolar transistor, this needs considerably more … WebTherefore, since the op-amp input current noise is proportional to the square root of the input bias current, Inoise = sq-rt(2 × q × IB), JFET input op amps (with IB comparable to CMOS and a low 1/f corner similar to a bipolar device) might be the best choice in obtaining the lowest possible total noise in high-input impedance applications.
