GATE Electronics and Communications (EC) 2022 Solved Paper

Consider the circuit shown with an ideal long channel nMOSFET (enhancement-mode, the substrate is connected to the source). The transistor is appropriately biased in the saturation region with V_GG and V_DD such that it actsas a linear amplifier. v_i is the small-signal ac input voltage. v_A and v_B represent the small-signal voltages at nodes A and B, respectively. The value of  $\frac{{\mathit{v}}_{\mathit{A}}}{{\mathit{v}}_{\mathit{B}}}$ ,is ________ (roundedoff to one decimal place).
