Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Superconductivity is an advantageous property observed in some materials, which entails an electrical resistance of zero at ...

Impulse relay turns on with an electrical impulse at the control input and turns off again with another impulse.

Abstract: A three-phase shunt active filtering algorithm based on the real ... The experimental setup is controlled by making use of simple op-amp-based analog circuits and digital signal processor ...

Abstract: Single-phase ac/dc or dc/ac systems are inherently subject to ... In view of this, this paper presents a symmetrical half-bridge circuit which utilizes the dc-link capacitors to absorb the ...

A novel supply-noise sensing (SNS) circuit is proposed to suppress the supply noise’s influence on output frequency. Based on these, a 1.2 V 2 GHz PLL circuit is implemented in 110 nm CMOS process.
