Abstract:

The silicon P-N junction is studied from a theoretical standpoint, then compared with actual characteristics. The dynamic resistance characteristic is determined, and typical circuits are presented that illustrate how this variable resistance can be used to control gain or attenuation electrically. It is shown that there are four basic characteristics of gain versus AGC voltage linear, logarithmic, logarithmic to the minus 1 power, hyperbolic. These characteristics depend on how the diodes are driven voltage or current source and where the diodes dynamic resistance appears in the circuits gain equation. Author
