If g is the transconductance, r is the resistance due to channel length modulation and if M2 has channel length modulation but M1 doesn’t, what is the voltage gain at node x?(a) (1/g || r) / (1/g + (1/g || r))(b) (1/g || r) / (1/g + (1/g || 2r))(c) (1/g || r) / (2/g + (1/g || r))(d) (1/g || r) / (1/g + (2/g || r))The question was asked by my college professor while I was bunking the class.Asked question is from MOSFET Amplifier with CD Configuration topic in section FET Amplifiers of Analog Circuits |

Answer» Correct choice is (a) (1/g || r) / (1/g + (1/g || r)) |
