Assume that the threshold voltage of the $$N$$-channel $$MOSFET$$ shown in figure is $$0.75$$ $$V.$$ The output characteristics of the $$MOSFET$$ are also shown

The voltage gain of the amplifier is

The common emitter amplifier shown in the figure is biased using a $$1mA$$ ideal current source. The approximate base current value is_____.

The value of $$R$$ for which the $$PMOS$$ transistor in Figure. $$Q$$ $$63$$ will be biased in linear region is

For the $$n$$-channel enhancement $$MOSFET$$ shown in figure,, the threshold voltage $${V_{th}}\,\, = \,\,2V.$$ The drain current $${I_D}$$ of the $$MOSFET$$ is $$4$$ $$mA$$ when the drain resistance $${R_D}$$ is $$1k\Omega .$$ If the value of $${R_D}$$ is increased to $$4\Omega ,$$ drain current $${I_D}$$ will become
