An IC CG amplifier is fed from a signal source with Rsig = ro/2, where ro is the MOSFET output resistance. It has a current-source load with an output resistance equal to ro. The MOSFET is operated at ID = 100 μA and has gm = 1.5 mA/V, VA = 10 V, Cgs = 0.2 pF, Cgd = 0.015 pF, and Cd b = 20 fF. As well, the current-source load provides an additional 30 fF capacitance at the output node. Find fH.

A MOSFET common-source amplifier has gm = 2.0 mA/V, ro = 100 KΩ, RD = 10 KΩ, Cgs = 2 pF, Cgd = 0.4 pF. The amplifier is fed from a voltage source with an internal resistance of 500 KΩ and the output is connected to a 10 KΩ load. If the lower cutoff frequency (fL) is 10 KHz, find the Gain-bandwidth product of this amplifier in (dB) KHz (ignore the sign). Approximate your answer to 2 decimal point accuracy.
