Experimenting with Op Amps: Open-Loop Output Resistance

WebbJames Bryant A digital multimeter, sometimes known as a digital voltmeter or DVM (slightly inaccurately as it measures amps and ohms as well as volts), is an instrument which is used for making electrical and … WebbThe measurement process can be greatly simplified by using a servo loop to force a null at the amplifier input, thus allowing the amplifier under test to essentially measure its own errors. Figure 1 shows a versatile circuit that employs this principle, employing an auxiliary op amp as an integrator to establish a stable loop with very high dc open-loop gain.
