The DS1842 integrates the discrete high-voltage components necessary for avalanche photodiode (APD) bias and monitor applications. A switch FET is used in conjunction with an external DC-DC controller ...

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 ...

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 ...
