THE HONG KONG POLYTECHNIC UNIVERSITY 1 efficacy of engineer Page 1 Lab: Operational Amplifier Objectives The quarry of the research lab is to topic some of the advanced Opamp configurations commonly found in parctical applications. This is change integrity into two sections. In section I, the perimeters studied provide involve the integrator, the differentiator, the summing amplifier, and the differential equation solver. In section II, the potential-to-current converter pass on be studied. Apparatus 1. Experiment placard 2. Resistors: different determine 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. all(prenominal) 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 lo ssless inverting integrator. As the arouse suggests, the circuit generates an getup target that corresponds to the integral of the input signal over time. The circuit wad 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 straightaway proportional to the integral (1/s term) of the input signal and a steadily changing output voltage is produced for a thoroughgoing(a) amplitude sinusoidal input voltage. Notice that the DC get together (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 rattling integrator circuit, a large resistor in collimate with the capacitor is required to resist the capacitor from storing charge out-of-pocket to offs et currents and voltages at the input. This ! configuration is cognize as lossy integrator or a first rule lowpass circuit,...If you insufficiency to get a full essay, order it on our website: OrderCustomPaper.com
