Q1: Generally, the gain of a transistor amplifier falls at high frequency due to theA internal capacitance of the device
B coupling capacitor at the I/P
C skin effect
D coupling capacitor at the O/P
ANS:A - internal capacitance of the device Stray capacitance between closely packed wiring and components can also reduce gain at high frequencies, as well as causing other problems such as instability and oscillation, so the practical upper limit of operation for an amplifier is affected by a number of causes. |
