Method for extending transistor logarithmic conformance |
摘要 |
The linear component appearing in the output of two logarithmic amplifiers connected for temperature compensation and having matched feedback semiconductor devices is cancelled in a resistor connected in series with a logarithmic device between the output and a point of reference potential so that a purely logarithmic voltage appears at their junction.
