Open or closed loop
WebIn electronic amplifiers, the phase margin (PM) is the difference between the phase lag φ (< 0) and -180°, for an amplifier's output signal (relative to its input) at zero dB gain - i.e. unity gain, or that the output signal has the same amplitude as the input. = (). For example, if the amplifier's open-loop gain crosses 0 dB at a frequency where the phase lag is -135°, … Web13 de set. de 2012 · Less expensive than their closed-loop cousins, open-loop current sensors are generally preferred in battery-powered circuits given their low-operating …
