Semiconductor indicator for voltage diagnostics in power amplifiers |
abstract |
A semiconductor indicator for quantitatively diagnosing voltage conditions in high power transistor devices is provided. The semiconductor indicator includes a first transistor and a second transistor, where an electrically active periphery of the second transistor is less than an electrically active periphery of the first transistor. The transistors are thermally coupled to one another and may be in close proximity. The second transistor detects the voltage of a node on the first transistor and may be monitored by infrared imaging. The breakdown voltage characteristic of the second transistor may not substantially change as the temperature in the first transistor increases. An optional control circuit monitors and detects the output voltage of the first transistor. |
