Hint: since we are assuming an ideal op amp, there is a virtual short-circuit between
input terminals.
Q4: Design a buck-boost
converter to provide an output voltage 12V from a source that varies 'between 10V-16V.
Given the load resistor is 10 2, assuming the frequency is 50 KHz and the output
voltage ripple is 1.5% Specify:
a. The duty ratio.
b. The value of inductor.
c. The value of capacitor.
Note: Determine the values of inductor and capacitor with DI only.
The circuit shown in Fig. 4 provides transfer characteristics with +7.5 V levels at the output vo.
When v 0 V, a current of 0.5 mA flows in the feedback resistor (R2) and a current of 1.0 mA
flows through the zener-diodes. Assume that the output saturation levels of the op-amp are ±12.0
V, the forward-drop voltage of the zener-diode is 0.7 V, and the value of R, is equal to R2.
