This is a cascade of a CG stage preceding a CS stage. For the CG stage, the voltage gain is gm * Rd. But after this stage, the signal gets amplified by the CS stage with a factor of –(gm2* Rd1). Hence, the overall voltage gain is the product of both the factors ie –(gm1 * Rd * gm2 * Rd1). Note that since channel length modulation is absent, ro is not present in the expression of gain.
