​​​​For the closed loop amplifier circuit shown below, the magnitude of open loop low frequency small signal voltage gain is $40$. All the transistors are biased in saturation. The current source $I_{S S}$ is ideal. Neglect body effect, channel length modulation and intrinsic device capacitances. The closed loop low frequency small signal voltage gain $\frac{v_{\text {out }}}{v_{\text {in }}}$ (rounded off to three decimal places) is $\_\_\_\_\_\_$.

  1. $0.976$
  2. $1.000$
  3. $1.025$
  4. $0.488$
