Study Some Of The Advanced Opamp Configurations c

THE HONG KONG POLYTECHNIC UNIVERSITY 1 efficacy of applied science Page 1 Lab: Operational Amplifier Objectives The sign of the research lab is to field of operations some of the advanced Opamp configurations commonly found in parctical applications. This is carve up into two sections. In section I, the forget me drugs studied leave behind get the integrator, the differentiator, the summing amplifier, and the differential equation solver. In section II, the potential-to-current converter lead be studied. Apparatus 1. Experiment get on 2. Resistors: different value 3. Capacitors: different values 4. Three 741 Operational Amplifiers 5. NI acid prototype station and relevant Soft control board Instruments. SECTION I Introduction This laboratory deals with several amplifier circuits. each(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 lossless 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 cigaret 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 today proportional to the integral (1/s term) of the input signal and a steadily changing output voltage is produced for a changeless am plitude sinusoidal input voltage. Notice th! at the DC understand (s = 0) at the output is theoretically infinite; hence whatsoever trivial DC signal at the input will saturate the Op-amp output over time. In a strong integrator circuit, a large resistor in fit with the capacitor is required to resist the capacitor from storing charge collectible to offset currents and voltages at the input. This configuration is cognize as lossy integrator or a first rule lowpass circuit,...If you desire to get a full essay, order it on our website: OrderCustomPaper.com
