The small signal equivalent circuit of a MOSFET amplifier at low frequencies is shown below. As a result of the DC bias the transistor has a transconductance value of gm = 4 mA/V. Let Rsig = 0.4 MΩ, RG = 1.5 MΩ, RD = 20 kΩ and RL = 20 kΩ. The three external capacitances have the following values: CC1 = 90 nF, CC2 = 0.4 μF and CS = 7 μF. Determine the value of the low cutoff frequency fL. Note: The dotted line indicates that the two nodes have the same voltage but no physical wire exists between them.
