| Abstract: | Zener diodes operated in the breakdown region have been investigated as transfer noise standards in the r.f. region. A close correlation has been found between the variation in excess noise ratio (e.n.r., dB) and the temperature coefficient of Zener diodes. In particular, diodes having zero temperature coefficient of voltage also have zero temperature coefficient of e.n.r. |
