Study Some Of The Advanced Opamp Configurations c

THE HONG KONG POLYTECHNIC UNIVERSITY 1 efficacy of engine room Page 1 Lab: Operational Amplifier Objectives The buttocks of the research lab is to demand some of the advanced Opamp configurations commonly found in parctical applications. This is divide into two sections. In section I, the roofys studied allow foring pose the integrator, the differentiator, the summing amplifier, and the differential equation solver. In section II, the emf-to-current converter will be studied. Apparatus 1. Experiment add-in 2. Resistors: different value 3. Capacitors: different values 4. Three 741 Operational Amplifiers 5. NI demigod prototype station and relevant Soft control board Instruments. SECTION I Introduction This laboratory deals with several amplifier circuits. distributively of the circuits in the lab requires some thinking to understand how the circuit works and its practical limitations. planimeter: The circuit in Fig. 1 is the lossless inverting inte grator. As the arouse suggests, the circuit generates an getup target that corresponds to the integral of the input signal over time. The circuit potty be analyzed utilize the standard Op-amp analysis techniques. Fig.

1 Inverting integrator circuit THE HONG KONG POLYTECHNIC UNIVERSITY 2 Faculty of Engineering Page 2 In the frequency domain, the widening voltage is depict as: out Vin sR C V 1 = ? 1 It can be seen that the output is at once proportional to the integral (1/s term) of the input signal and a steadily changing output voltage is produced for a complete(a) amplitude sinusoidal input voltage. Notice that the DC cause (s = 0) a! t the output is theoretically infinite; hence any trivial DC signal at the input will saturate the Op-amp output over time. In a true integrator circuit, a large resistor in match with the capacitor is required to resist the capacitor from storing charge receivable to offset currents and voltages at the input. This configuration is cognize as lossy integrator or a first rule lowpass circuit,...If you trust to get a full essay, order it on our website: OrderCustomPaper.com
