1.	In a circuit shown in the figure, the transistors M1 and M2 are operating in saturation. The channel length modulation coefficients of both the transistors are non-zero. The transconductance of the MOSFETs M1 and M2 are gm1 and gm2, respectively, and the internal resistance of the MOSFETs M1 and M2 are r01 and r02, respectively.Ignoring the body effect, the ac small-signal voltage gain (∂Vout / ∂Vin) of the circuit is:
A.	\(- {g_{m2}}\left( {\frac{1}{{{g_{m1}}}}\|\|{r_{02}}} \right)\)
B.	\(- {g_{m2}}\left( {\frac{1}{{{g_{m1}}}}\|\|{r_{01}}\|\|{r_{02}}} \right)\)
C.	\(- {g_{m1}}\left( {\frac{1}{{{g_{m2}}}}\|\|{r_{01}}\|\|{r_{02}}} \right)\)
D.	\(- {g_{m2}}\left( {r_{01}\|\|{r_{02}}} \right)\)
Answer» C. \(- {g_{m1}}\left( {\frac{1}{{{g_{m2}}}}\|\|{r_{01}}\|\|{r_{02}}} \right)\)
