Common source mosfet amplifier midband equivalent circuit

A simplified small-signal circuit schematic of a common-source MOSFET amplifier at midband, with the internal capacitors omitted. Show an n-channel MOSFET with gate on the left, drain on the right or upper right, and source grounded. A sinusoidal source labeled Vsig feeds the gate through a series resistor Rsig. A resistor RG connects the gate node to ground. At the drain, show a controlled current source labeled gm*vgs and a resistor labeled RL_prime to ground. Mark the output voltage Vo at the drain. Clean black line-art schematic, no capacitors present.
