You would like to measure the output pin of your circuit with a spectrum analyzer, but the pin needs to be biased to be in a standard operation mode. How would you bias this circuit without affecting ...
The final part of this series will start with bias servo circuits for automatic set up. The FETs pinch off or threshold voltage can vary widely for the same part number. Depending on the fabrication ...
Bias circuits for class AB buffers (Fig. 1a) can take several forms. One alternative (not necessarily the best) is usually called the “old VBE doubler” (Fig. 1b). The main purpose of these circuits is ...
