Neglecting Channel Length Modulation, if the aspect ratio of the MOSFE

1.	Neglecting Channel Length Modulation, if the aspect ratio of the MOSFET increases, the gain of the follower stage will _________(a) increase(b) decrease(c) increases proportionately(d) doesn’t get affectedI have been asked this question during an online exam.The doubt is from MOSFET Amplifier with CD Configuration in division FET Amplifiers of Analog Circuits
Answer» Right ANSWER is (a) increase Easy explanation: The square root of the aspect RATIO is directly proportional to the transconductance of the MOSFET. If it increases, the transconductance increases and hence according to the EXPRESSION of the voltage gain of a follower STAGE gain increases.
