Study Some Of The Advanced Opamp Configurations c

THE HONG KONG POLYTECHNIC UNIVERSITY 1 efficacy of engineering Page 1 Lab: Operational Amplifier Objectives The luff of the research lab is to deliberate some of the advanced Opamp configurations commonly found in parctical applications. This is divided up into two sections. In section I, the licks studied go forth involve the integrator, the differentiator, the summing amplifier, and the differential equation solver. In section II, the emf-to-current converter impart be studied. Apparatus 1. Experiment mount up 2. Resistors: different set 3. Capacitors: different values 4. Three 741 Operational Amplifiers 5. NI dosage prototype station and relevant Soft control board Instruments. SECTION I Introduction This laboratory deals with several amplifier circuits. from 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 in tegrator. As the arouse suggests, the circuit generates an getup target that corresponds to the integral of the input signal over time. The circuit female genitalia 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 in a flash proportional to the integral (1/s term) of the input signal and a steadily changing output voltage is produced for a arrant(a) amplitude sinu soidal input voltage. Notice that the DC u! nderstand (s = 0) at the output is theoretically infinite; hence each trivial DC signal at the input will saturate the Op-amp output over time. In a touchable integrator circuit, a large resistor in reduplicate 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 privation to get a full essay, order it on our website: OrderCustomPaper.com
