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 $I_{SS}$ is ideal. Neglect body effect, channel length modulation and intrinsic device capacitances.
The closed loop low frequency small signal voltage gain $\frac{v_{out}}{v_{in}}$ (rounded off to three decimal places) is
