measured to be 32dB, of 100k Ohms, and 3k Ohms, respectively. The designer used input and output coupling capcitors with values of 1uF and 100uF, respectively. The amplifier circuit's PCB layout was properly designed, thus minimizing the wiring capacitances. The device capcitances
"A common emiiter amplifier (Fixed Bias) is currently under test to determine its bandwidth in the unloaded case. In the bandpass region ,the amplifier's voltage gain, input impedance, and output impedance are measured to be 32dB, of 100k Ohms, and 3k Ohms, respectively. The designer used input and output coupling capcitors with values of 1uF and 100uF, respectively. The amplifier circuit's PCB layout was properly designed, thus minimizing the wiring capacitances. The device capcitances are measured as follows: C_BE = 1pF, C_BC = 8pF, and C_CE = 1pF. Assuming a voltage source resistance of 50 Ohms, determine the higher cutoff frequency due to the output circuit."
