It would be best to think in terms of gate to channel. In your equation #1, that might only hold true in one particular channel condition. Once the channel pinches off the drain doesn't under go massive capacitance changes. I'd be suspicious.

FETs (JFETs or MOSFETs) are devices with three terminals: source, gate, and drain. FETs control the flow of current by the application of a voltage to the gate, which in turn alters the conductivity between the drain and source. FETs are also known as unipolar transistors since they involve single-carrier-type operation. Th…
