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 ...

Abstract: This paper presents a 7-MHz CMOS RC frequency reference. It consists of a frequency-locked loop in which the output frequency of a digitally controlled oscillator (DCO) is locked to the ...

Abstract: The three-phase three-wire stand-alone inverter is required to have short-circuit fault ridethrough ability to achieve continuity of power supply. Generally the inverter works in ...

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.
