"WebThe noise of op-amps is Gaussian with constant spectral density, or “white”, over a wide range of frequencies, but as frequency decreases the spectral density starts to rise at about 3 dB/octave. This low-frequency noise characteristic is known as “1/f noise” since the noise power spectral density goes inversely with frequency (actually 1/f g ). " - Op amp frequency range

But which one is the best for your … WebThe amplitude-response and phase-response curves for a typical operational amplifier are given in the figure below. The low-frequency gain of the amplifier is 100 dB, or 100,000, and the low-frequency phase shift is essentially zero. At some frequency (often below 10 Hz as in this case) the gain begins to fall off, usually at 6 dB per octave.
