In single transistor amplifier design, it is observed that the voltage gain will always decrease as the load resistance increases. True False The saturation region of MOSFET indicates that the drain current no longer depends on the source-drain voltage while the saturation region of BJT indicates that the collector current no longer depends on the collector-emitter voltage. True False A bipolar junction transistor can be connected to behave like a diode while a field effect transistor can not be connected to behave like a diode. True False A voltage follower circuit is usually designed to have the power gain slightly less than 1 with any passive load.
