Consider the circuit shown with an ideal long channel nMOSFET (enhancement-mode, substrate is connected to the source). The transistor is appropriately biased in the saturation region with VGG and VDD such that it acts as a linear amplifier. vi is the small-signal ac input voltage. vA and vB represent the small-signal voltages at the nodes A and B, respectively. The value of vA/vB is ________ (rounded off to one decimal place).
Correct : 0.5
