During the first half of the 20th century radio technology was booming, albeit restricted by the vacuum tube technology of the time which made radios cumbersome in size and power needs. The ...

Tunnel diodes are heavily doped P-N diodes in which electron tunneling from the conduction band in the N-type material to the valence band in the P-type region produces a region of negative resistance ...

A new tunnel diode/transistor circuit topology is reported, which both increases speed and reduces power in differential comparators. This circuit topology is of special interest for use in direct ...

The RCA tunnel diode inverter circuit The resulting circuit produces a 15kHz oscillation with 4.5v peaks, and has just enough power to light an LED. While it might seem pointless to barely light ...
