WebThe Body Effect In an integrated circuit using MOSFET devices, there can be thousandsor millionsof transistors. As a result, there are thousands or millions of MOSFET source terminals! But, there is only oneBody (B)— the Silicon substrate. WebBJT. There are two types of MOSFET and they are named: N-type or P-type. BJT is of two types and they are named as: PNP and NPN. MOSFET is a voltage-controlled device. BJT is a current-controlled device. The input resistance of MOSFET is high. The input resistance of BJT is low. Used in high current applications.
