Find the midband gain Aₘ and the upper 3-dB frequency fₕ of an integrated-circuit CS amplifier fed with a signal source having an internal resistance Rₛᵢ = 20 kΩ. The amplifier has Rₗ = 20 kΩ, gₘ = 2 mA/V, rₒ = 20 kΩ, Cₛ = 20 fF, and C = 5 fF. Also, find the frequency of the transmission zero.
For the CS amplifier specified in Example 10.1, find the values of Aₘ and fₕ that result when the load resistance is reduced to 10 kΩ.
