A novel variable inductor using a bridge circuit is proposed. Because of a bypass switch MOSFET placed at a balance point, the effect of the switch resistance which is a penalty of the variable ...

So when I recently came across an early 1970s HP 7041A X-Y recorder while clearing out my parents’ attic, I knew that I just ...

An active power-factor correction (PFC) circuit is presented that employs a newly proposed resistor-free zero-current detection (ZCD). While the conventional ZCD requires either a sensing resistor or ...

JCSC covers mathematical foundations to practical engineering design in circuits, systems, and computers. Research papers, survey, letters and tutorial papers are welcome ...

A team of researchers from KAIST and Seoul National University has now developed a electronic ink that enables room-temperature printing of variable-stiffness circuits capable of switching between ...
