Constant current generator

摘要

The generator has an amplifier (12) and a transistor (MNI) controlled by the amplifier output and connected between the current reflector and the first resistance (Ri). A second resistance (Re) is connected between the output (MP3) of the reflector and the amplifier input. A filter (14,16) suppresses all alternative high frequency components of the amplifier output with respect to a mass (GNDI). Used in a numero-analog converter
