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 ...

Santa Clara, Calif. – National Semiconductor bills its LM5008 as the industry's first 100-volt rated, buck bias regulator, which operates at up to 90 percent efficiency. The latest addition to the ...

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 ...
