Op amp unity gain stability
WebThis paper reports a new design of a low power two stage operational amplifier with Miller compensated topology for enhancing stability. The circuit is designed and simulated in Tanner EDA tool using 45 nm. CMOS technology. A significant reduction in power and enhancement of unity gain BW is achieved with a satisfactory phase margin. Several … Webis the unity gain bandwidth of the op amp. In order to maintain stability, the A OL curve must intersect the 1/β curve when the 1/β curve is flat (assuming a unity gain stable op amp). If the A OL curve intersects the 1/β curve when the 1/β curve is rising, as shown by the dashed line in Figure 4, the circuit may oscillate. This gives us ...

WebOp-amps are used with feedback, this makes it possible for them to oscillate, which is bad unless you are designing an oscillator! The phase margin basically states how stable the op-amp is, i.e. phase angle distance from the point of oscillation, in the worst-case configuration of unity gain. WebOp-amps are often used in a simple voltage follower configuration. However, this is not the best configuration in terms of capacitive loading and potential risk of oscillations. …
