Miller's theorem is used in the high-frequency analysis of BJTs and FETs.
One characteristic of amplifiers is that the sum of the voltage gain and the bandwidth is always constant when the roll-off is –20 dB/decade.
Bandwidth is the difference between fcl and fcu.
The lower and upper critical frequencies of an amplifier can be determined using the step-response method.
The term "dBm" means decibels referenced to 1 mW of power.
The basis for the decibel unit stems from the logarithmic response of the human ear to the intensity of sound.
A decade of frequency change is a change by a factor of 10.
At the cutoff frequency the output is down 20 dB.
