However, the development of FPGAs has created an important alternative to ASICs and DSPs. The flexibility and integration possibility is two important advantages among others.

Battery-powered trends in consumer electronics, transportation, and renewable energy sectors increase demands on DC/DC converter technology. Higher switching frequency and efficiency reduces solution size and cost, while increasing power capabilities. Still, switching noise remains the primary drawback associated with any DC/DC converter. Reducing a converter’s input ripple helps prevent switching noise from spreading to other systems on a shared DC power bus.

A switch on the secondary side can be turned off and the converter will take the characteristics of a boost converter.

A dynamic compensation technique is introduced for hysteretic DC/DC converters to improve transient response in case of output loading variation. Therefore, the compensation control circuit with the proposed dynamic compensation technique contains adaptive compensation capacitance and resistance, which can be changed according to output loading current. As a result, the compensation pole-zero pair will be moved toward to higher frequencies to incre

In power management ICs, the aging of power MOSFETs affects the reliability of the overall system. Traditionally, it is determined by the measurement of the threshold voltage and turn-on resistance to detect the state of healthy.

The harvested power from thermal energy is very low. In order to work under low voltage situation, the conventional architecture uses low threshold voltage (VTH) transistors in the startup circuit, because transistors will only work when the input voltage is greater than the threshold voltage. However, the leakage current of the low VTH transistor is large. A negative voltage generator can be used to alleviate this

Generally, basic switching regulators (e.g., buck, boost) are not capable of using the entire battery output characteristics effectively (e.g., 2.7–4.2 V for Li-ion) to provide a fixed output voltage (e.g., 3.3V). In this work, an average-current-mode non-inverting buck-boost dc-dc converter is introduced, which can use the full-range output voltage of Li-ion battery with the advantages of high power efficiency, faster transient r
