Circuit arrangement, especially integrated bipolar BIAS circuit - comprises several collector current sources which are respectively formed by transistor, whose base is respectively connected with output of reference voltage source

摘要

The circuit arrangement generates an output voltage (V0) which is independent of the actual value of the supply voltage (VCC), and comprises a device (11) for generating a reference voltage, and one or several collector current sources which are respectively formed by a transistor (20, 30, 40). The base (21, 31, 41) of each transistor is respectively connected with the output (14) of the reference voltage source. The emitter (22, 32, 42) of each transistor is connected with ground (13), and the respective collector (23, 33, 43) with a voltage source (12) for the supply voltage, preferably over a resistance (25, 35, 45).
