DC voltage generating circuit arrangement - comprises third bipolar transistor with collector connected with supply voltage source, and emitter connected over resistance with collector of at least one second transistor, and base of first transistor

摘要

The circuit arrangement includes at least two crosswise connected, bipolar transistors, of which a first transistor (20) has an emitter (21) connected with ground (12). One or several second bipolar transistors (30) have a relative emitter surface area, whereby the emitter (31) is connected over at least one resistance (35, 36) with ground. A third bipolar transistor (40) has a collector (43) connected with a supply voltage source (11), and an emitter (41) connected over a resistance (45) with the collector (33) of the at least one second transistor, and the base (22) of the first transistor.
