Choose the correct statement(s)i) The gate circuit impedance of MOSFET...
Gate Circuit Impedance:
- MOSFET: The gate circuit impedance of a MOSFET is higher than that of a BJT. This is because the MOSFET gate is insulated from the channel by a thin oxide layer, which results in a higher impedance.
- BJT: On the other hand, the gate circuit impedance of a BJT is lower compared to a MOSFET.
Switching Losses:
- MOSFET: The MOSFET has lower switching losses than that of a BJT. This is because the MOSFET has a high input impedance, which results in reduced power losses during switching.
- BJT: In contrast, the BJT has higher switching losses due to its lower input impedance.
Therefore, option 'C' is the correct choice as it correctly states that the gate circuit impedance of a MOSFET is higher than that of a BJT, and the MOSFET has lower switching losses compared to a BJT.
