The added bonus? All of these games are relatively expense-free, but they’ll substantially level up your gaming experience...Real op amps have errors that behave like voltage or current inputs. For example, in the follower-with-gain configuration (Figure 30-21), if a sufficiently sensitive high impedance meter is used, a DC output will be found to exist—even if there is no signal input—and it will be proportional to 1/β (i.e., 1 + R f /R), as if it were produced by a battery in series with …Advertisement. Today, three test-circuit topologies are commonly used for bench and production testing of DC parameters in operational amplifiers. These three topologies are 1) the two-operational-amplifier test loop, 2) the self-test loop, sometimes called a false-summing junction test loop, and 3) the three op-amp loop.Amps do not contain any volts.
