QUESTION 15
Two amplifiers A and B are cascaded through capacitor coupling
as abovd circuit. The amplifier A has gain of 16dB, input impedance
of 11Kohm, and output impedance of 26Kohm. The amplifier B has gain
of 20dB, input impedance of 31Kohm and output impedance of 5kohm.
The lower corner frequency
f L =4KHz.
If the capacitor is chosen for dominant pole, determine the value
of the capacitor in pF
QUESTION 16
Two amplifiers A and B are cascaded through capacitor coupling
as abovd circuit. The amplifier A has gain of 16dB, input impedance
of 14Kohm, and output impedance of 11Kohm. The amplifier B has gain
of 20dB, input impedance of 31Kohm and output impedance of 2kohm.
The lower corner frequency
f L =39KHz.
If the capacitor is NOT chosen for dominant pole, determine the
value of the capacitor in pF
