It’s the end of the year, and a few hardy souls gather in a hackerspace to enjoy a bit of seasonal food and hang out.

Experimental results of an oscillator circuit operating at 2-3 Gc with the suppression of LF oscillation are described. Data on the high-current tunnel diodes (50 \sim 100 ma) used are given.

but also uniquely tackles the prevention of the Zeno phenomenon. At last, the stabilization of tunnel diode circuit is conducted to confirm the validity and the effectiveness of our strategy.

Mostly-Analog editor Andy Turudic takes a look at the original 1963 ISSCC paper that described the world’s first CMOS process ...

Three essentially different types of low-noise amplifier - the tunnel diode, the quadrupole and the varactor-diode parametric amplifier - are described in some detail. Of these, the parametric ...
