An n-channel MOSFET has the following parameters: μn = 400 cm2 /V−s tox = 500Å L = 2 μm W = 20 μm VT = +0.75 V Assume the transistor is biased in the saturation region at VGS = 4 V. (a) Calculate the ideal cutoff frequency. (b) Assume that the gate oxide overlaps both the source and drain contacts by 0.75 μm. If a load resistance of RL = 10 kΩ is connected to the output, calculate the cutoff frequency.
