Ge tranny - temperature dependence

[yeeshkul]

Let's say i set up a bias voltage for a Ge tranny (FF, TB, ...) at room temperature. After that, when the temperature is rising, does the collector bias voltage go up or down?

[zachomega]

As the temperature rises, the transistor will draw more current which will create a larger voltage drop at the collector reducing its voltage. 

However, a well designed circuit will minimize this effect usually by means of some sort of feedback or clever biasing scheme.

Temp goes up:

-Current Draw Up
-Voltage Drop Up
-Voltage Down
-Sound ... Who Knows...
