Q. What is Open-loop voltage gain?
The op amp amplifies the difference vd between the voltage on the noninverting (+) terminal and the inverting (-) terminal; see Figure. The term "open loop" implies that there is no external feedback connection between the output and either of the inputs. A is defined as the ratio of the change in output voltage to the change in differential input voltage, usually for a load resistance of no less than 2k. A typical value for A is 2 × 105.
Q. What do you mean by Superposition and linearity? Mathematically a function is said to be linear if it satisfies two properties: homogeneity (proportionality or scaling) and
Q. Effect of feedback on stability? Let us consider the direct transfer function of the unstable first-order system of Figure (a). The transfer function is given by whe
