Given the circuit, explain the effect of having the capacitor to the output. why does the output have spikes/distortion? Please provide an equation that will help explain this.

The buck converter with resistive load has the input voltage of 30[V], the output voltage of 10[V] (constant), and the switching frequency of 40 [kHz]. If the output average power is 25[W], then determine the size of the inductor such that the minimum inductor current is 25 % of the average inductor current.

Give example with aid of diagrams and explain the usage of capacitive transducer as: i) Pressure sensor ii) Displacement sensor and What are the advantages of piezoelectric compare to capacitive transducers? Provide an example of electronic device that uses piezoelectricity and explain its concept based on the type of piezoelectric effect.

4. A biased clamper is connected to a rectangular AC input with 20V on the positive half cycle and -10V on the negative half cycle.

Determine the forward voltage and forward current of a diode in a circuit. The circuit is composed of a dc voltage source with its positive terminal of 10V connected in series to a 1Kohms resistor and the anode of a diode. The cathode of the diode is connected to ground. Use ideal device model approach. Draw the circuit and show your solution/s.
