See Part 1, Part 2, and Part 3 of this series. The previous FET circuits pertained to voltage-controlled signal amplitude circuits. That is, the input signal’s amplitude can be changed at the output ...

Scientists at Germany’s Jülich Institute for Energy and Climate Research (IEK-5) have raised the open circuit voltage of perovskite solar cells to a record of 1.26 V. The researchers say open circuit ...

Applications ranging from consumer electronics to high-power energy-conversion systems leverage the benefits of dc-dc power converters in their designs. Among these, flyback converters are popular for ...

There have been many different ideas presented for increasing the acoustic output of a piezo buzzer or ultrasonic transducer. Most of them involve rather complicated circuitry that drives up the total ...
