The voltage gain of an amplifier decreases 20dB/dacade above 20KHz. If the mid band voltage gain is 68dB, What is the ordinary voltage gain at 20MHz?

Answer»

The mid band gain in \(\frac{V}{V_0}\)

Mid band gain = 20 log Av

68 = 20 log Av

log Av = 68/20

log Av = 3.4

Av = 103.4

Av = 2511.88 V/V0
