Operational Amplifier Basics - Op-amp tutorial

WebA unity gain buffer amplifier may be constructed by applying a full series negative feedback (Fig. 2) to an op-amp simply by connecting its output to its inverting input, and connecting the signal source to the non-inverting input (Fig. 3). Unity gain here implies a voltage gain of one (i.e. 0 dB), but significant current gain is expected. In this configuration, the entire … WebThus, the Active Low Pass Filter has a constant gain A F from 0Hz to the high frequency cut-off point, ƒ C.At ƒ C the gain is 0.707A F, and after ƒ C it decreases at a constant rate as the frequency increases. That is, when the frequency is increased tenfold (one decade), the voltage gain is divided by 10. In other words, the gain decreases 20dB (= 20*log(10)) …
