This paper proposes a new negative impedance converter (NIC) with an emitter follower (EF) circuit. Two types of NICs with EF and without EF, designed to generate a negative capacitance of -100 pF, ...

The proposed design can function with an input common-mode voltage range that includes the negative supply rail. Simulation results show that the proposed CFIA achieves an open loop gain of 115dB, ...

NEW ORLEANS (press release) – Improving the rail and intermodal supply chain, The New Orleans Public Belt Railroad (NOPB) has announced a strengthened partnership with Freedom Intermodal Tank Services ...

A £500 million five-year contract for British Steel to supply rail track for the country’s railways has been hailed as the confidence booster that the sector needs.

Operations of the Gyeongui-Jungang Line, a commuter rail service of the Seoul metropolitan area, were suspended or delayed Friday due to a power supply accident, its operator Korail said. The ...

Why is it called a coronavirus? First described in detail in the 1960s, the coronavirus gets its name from a distinctive corona or 'crown' of sugary-proteins that projects from the envelope ...

In this video, we will showcase a universal input (85V-260V AC) to 12V-3A DC Flyback power supply, delivering 36W of stable output power. The design uses an affordable PWM controller and an external ...
