A boost converter is required to have an output voltage of 8 V andsupply a load current of 1 A. The input voltage varies from 2.7 to4.2 V. A control circuit adjusts the duty cycle to keep the outputvoltage constant. If the switching frequency is 200 kHz, determine:i. a value for the inductor such that the variation in inductorcurrent is no more than 40% of the average inductor current forall operating conditions.ii. a value for the capacitor such that the output voltage ripple isno more than 2%.iii. in case the OFF period is reduced by 30% for constantfrequency operation, find the new output voltage

Transform and draw the equivalent small signal circuit model using ONLY theHYBRID-PI model.

Define ICBO and ICEO. How are they different? How are they related? Are they typically close in magnitude?

Buck Converter Design Power supplies for telecommunications applications may require high currents at low voltages. Design a buck converter that has an input voltage of 3.3 V and an output voltageof 1.2 V. The output current varies between 4 and 6 A. The output voltage ripple mustnot exceed 2 percent. Specify the inductor value such that the peak-to-peak variation in inductor current does not exceed 40 percent of the average value. Determine the required rms current rating of the inductor and of the capacitor. Determine the maximum equivalentseries resistance of the capacitor.

Use multi-vibration circuits and create a signal generator that produces a square, triangular, and sinusoidal waveform with a frequency of 1kHz. Show work for theoretical layout. Also, use a switch for each waveform.

In a Wien bridge oscillator circuit, resistor and capacitor form a series branch and a parallel branch. The value of the resistor is 200 ohm and the value of the capacitor is 10 mF. Determine the frequency of oscillation for the Wien Bridge oscillator circuit.
