Operational Amplifier

An operational amplifier also called op amp is an integrated circuit or analog circuit that takes input as a differential voltage and produces output as a single-ended voltage. It is an IC that can amplify weak electric signals.An op amp has one output pin and two input pins. The basic role of an opamp is to amplify the voltage difference between the two input voltages. It is also used in filtering or to perform mathematical operations or in signal conditioning.

Problem 2: Consider controlling the Omron G5LE-1 5VDC power relay, shown below, using an Arduino in the following circuit. A relay has windings that when energized cause a magnetic field, which mechanically closes the contact side of the relay, so it acts as an electronically controlled switch. One benefit of a relay is that the switch on the contact side is electrically isolated from the coil on the control side of the relay. This advantage of electrical isolation comes at a cost. Relays do not switch states quickly like transistors. Based on its data sheet, the Omron G5LE-1 5VDC has a coil resistance of 63N (at DC, consider the coil side of the relay as a resistor). Select the base resistance to ensure the P2N222A BJT is deep into saturation when the relay is energized (meaning current is flowing through its windings). o Note: It is safe to operate the Omron G5LE-1 at up to 130% of its rated voltage of 5VDC in its entire operating temperature range. Assume VcE sat = 0.2V for the BJT.…

2. The parameters of a certain transformer are to be found. Following the procedure as outlined in the introduction under the first order low frequency model section: The resistance of the primary winding of a certain transformer is found to be R1 = 388 Q, while the resistance of the secondary winding is R, = 0.9 Q. A 200 Hz, 5 volt peak-to-peak sinusoid, V1, is applied to the primary while the secondary is left open-circuited. The primary current, I,, entering at the dot is measured to be 1.07 milliamps peak-to-peak, lagging the voltage by nearly 83°. The open circuit voltage across the secondary, V20c, is measured to be 0.155 volts peak-to-peak. The sinusoid driving the primary is removed and a 200 Hz, 5 volt peak-to-peak sinusoid, V2, is applied to the secondary while the primary is left open-circuited. The secondary current, I2, entering at the dot is measured to be 206 milliamps peak-to-peak, lagging the voltage by 87°. From these measurements, estimate the self-inductances, L,…
