Which of these statements is false?
(a) The open loop gain AOL(f) dB is approximately constant from 0Hz to fo
(b) When input signal frequency and f is equal to break frequency fo, the gain frequency is called -3dB frequency
(c) The open loop gain AOL(f) dB is approximately constant upto break frequency fo, but there after it increase 20dB each time there is a tenfold increase in frequency.
(d) At unity gain crossover frequency, the open loop gain AOL(f) dB is zero
I got this question in my homework.
This interesting question is from Open-Loop Voltage Gain as a Function of Frequency in section Practical Limitations of Op Amp Circuits of Linear Integrated Circuits
