 10.50 A particular BJT operating at 2 mA is specified to have fT = 2 GHz, Cμ = 1 pF, rx = 100 Ω and β = 120.
The device is used in a CE amplifier operating from a very-low-resistance voltage source. (a) If the midband gain obtained is −10 V/V, what is the value of fH?
 (b) If the midband gain is reduced to −1 V/V (by changing vR1L), what fH is obtained?
