Study Some Of The Advanced Opamp Configurations c

THE HONG KONG POLYTECHNIC UNIVERSITY 1 efficacy of plan Page 1 Lab: Operational Amplifier Objectives The fool of the research lab is to teach some of the advanced Opamp configurations commonly found in parctical applications. This is divide into two sections. In section I, the traffic circles studied allow include the integrator, the differentiator, the summing amplifier, and the differential equation solver. In section II, the emf-to-current converter willing be studied. Apparatus 1. Experiment poster 2. Resistors: different set 3. Capacitors: different values 4. Three 741 Operational Amplifiers 5. NI window glass prototype station and relevant Soft control board Instruments. SECTION I Introduction This laboratory deals with several amplifier circuits. to each one 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 integra tor. 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 straightway proportional to the integral (1/s term) of the input signal and a steadily changing output voltage is produced for a everlasting amplitude sinusoidal input voltage. Notice that the DC infer (s = 0) at the output is theoretically infinite; hence whatsoever trivial DC si! gnal at the input will saturate the Op-amp output over time. In a reliable integrator circuit, a large resistor in analog with the capacitor is required to resist the capacitor from storing charge imputable to offset currents and voltages at the input. This configuration is cognize as lossy integrator or a first rule lowpass circuit,...If you emergency to get a full essay, order it on our website: OrderEssay.net
