The circuit also offers typical offset voltage of 5 µV, offset drift of 20 nV/°C, and equivalent input-noise voltage of 9 nV at 0.1 Hz. IC 1 , a Cirrus Logic CS3301 low-voltage, differential-input, ...

Scientists at the University of Cambridge in the UK have built a high-gain terahertz amplifier by adapting a 2.9 THz quantum cascade laser (QCL). An antireflective coating was deposited on the QCL ...
