Quiescent current compensation circuit has working point circuit for setting working point of mirror circuit for current mirroring of charging current flowing through charging capacitor

摘要

The circuit has a charging capacitor (8) connected to a signal output (A) of the driver output stage (T), a charging current mirror circuit (9) for current mirroring of a charging current flowing through the charging capacitor, with two mirror transistors (10,11) whose control connections are connected to the charging capacitor, and a working point circuit (38) for setting the working point of the mirror circuit.
