Introducing the Vacuum Transistor: A Device Made of Nothing

http://www.duncanamps.com/technical/ltspice.html Webbaddition, drift rates are far superior to vacuum tube circuits allowing a 0.5 volt full scale range which is impractical with most vacuum tubes. The low-leakage, low-noise 2N4340 is an ideal device for this application. TL/H/6791–8 HI-FI Tone Control Circuit (High Z Input) The 2N3684 JFET provides the function of a high input fmr shadow chica

WebbThe pressure range of XHV is usually defined as 10 -12 mbar and lower, while UHV is between 10 -7 and 10 -12 mbar, and HV between 10 -7 and 10-3 mbar. XHV is associated with the levels found in outer-space in the form of geo-stationary orbiting satellites, UHV with high-energy physics and nuclear research, such as that being conducted at CERN ... Webb23 maj 2012 · Vacuum tubes went the way of the dinosaurs in the 1960s, but researchers have now brought them back to life, creating a nano-sized version that's faster and hardier than the transistor. It's even able to survive the harsh radiation of outer space. Developed early last century, vacuum tubes offered the first easy way to amplify electric signals.
