Operational amplifier with negative impedance of the constraints
Bad people, but made history on the occasion is impossible. Current jumped more than a current value of the food after the second op amp can be normal J led by the designated circuit current limit f1 deleted. In order to exceed the limit value of the current Buzhi Yu, Ping-taking can be gradually reduced u. Value measures, until u. : 0 so far. It should be noted that if the power;;;} t those of the ear, etc. calculations collapse sent a large din plate impedance is shed worm article Xing women can not artificially reduced to zero voltage or the output value of short-term off-side, you can not achieve positive and negative resistance End resistance barrier offset. If the power supply through the resistor divider can be adjusted nine input voltage, and can. The flow of power to maintain access, hence destroy the voltage regulator output to zero value, you can achieve positive and negative resistance of the frogs arrived blame. Table 7 sets of data represent the results of different values. Table 7 Table 7 mA table for the resistance. I ffJ ~ JJKVL experience symptoms all the data to prove that its results are basically correct. Visible, with the negative impedance amplifier circuit is implemented in the short-circuit characteristics. This feature can be used to offset some of the components installed Tiao or impedance in the positive resistance, in order to achieve the purpose of the equivalent of superconducting circuits. 2.5 exchange information, the capacitance of the parallel circuit shown in Figure 8, taking CD0.5F, = R2 = l000Q,, = 300Hz,[link widoczny dla zalogowanych], U = 3V, auxiliary power supply voltage V + = 8.3V, V one by one 9. 3V, adjustable capacitance C can be observed when the C transferred from 0 to 0.5F, the current from 3mA dropped to near zero value, then the measured U = U2 = 3.4lV, profits from the Figure 8 circuit can resistance of the circuit is implemented in parallel with similar results. 3 Conclusion Zhu 8 spin-off from the above experiment can confirm, Sichuan op amp output impedance to achieve eradication of negative polarity side, not the way the two can achieve a negative output impedance effect, from the phenomena that it would be polarity, feedback resistance, external applied voltage, the op amp auxiliary power supply voltage, AC frequency, load resistance and other effects; but in fact, it is subject to their own performance, training and benefits that open loop operation. Polarity input terminal,[link widoczny dla zalogowanych], communication bandwidth and lower output saturation voltage and maximum output current constraints. These factors influence each other and check each other. When to meet the conditions, the op amp can achieve a negative resistance effect, people can use this feature implemented in the circuit some special requirements, such as pure electric power Viagra Viagra Effect of the coil to achieve such properties. In short, although H has been applied before the negative resistance, but with the realization of negative impedance amplifier,[link widoczny dla zalogowanych], the performance parameters of its components, components,[link widoczny dla zalogowanych], structural parameters, the auxiliary voltage, load resistance,[link widoczny dla zalogowanych], the feedback voltage, power frequency, how to select, set H and negative impedance in the circuit and parallel applications, the problem needs further research to explore.
