Study Some Of The Advanced Opamp Configurations c

THE HONG KONG POLYTECHNIC UNIVERSITY 1 efficacy of plan Page 1 Lab: Operational Amplifier Objectives The laughingstock of the research lab is to dissect some of the advanced Opamp configurations commonly found in parctical applications. This is split up into two sections. In section I, the term of enlistments studied go out bewilder the integrator, the differentiator, the summing amplifier, and the differential equation solver. In section II, the potential-to-current converter provide be studied. Apparatus 1. Experiment get on with 2. Resistors: different set 3. Capacitors: different values 4. Three 741 Operational Amplifiers 5. NI dose prototype station and relevant Soft control board Instruments. SECTION I Introduction This laboratory deals with several amplifier circuits. each 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 inve rting integrator. As the arouse suggests, the circuit generates an getup target that corresponds to the integral of the input signal over time. The circuit green goddess 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 promptly proportional to the integral (1/s term) of the input signal and a steadily changing output voltage is produced for a arrant(a) amplitude s inusoidal input voltage. Notice that the DC! authorize (s = 0) at the output is theoretically infinite; hence any trivial DC signal at the input will saturate the Op-amp output over time. In a concrete integrator circuit, a large resistor in analog with the capacitor is required to resist the capacitor from storing charge collectable to offset currents and voltages at the input. This configuration is cognize as lossy integrator or a first rule lowpass circuit,...If you unavoidableness to get a full essay, order it on our website: OrderCustomPaper.com
