voltage stabilisation circuit for integrated power driver

摘要

The voltage stabilisation circuit uses the current source transistor (TQ), used in the current driver difference amplifier circuit with a pair of emitter-coupled switching transistors (T',T''), as the setting element for a regulating circuit. The latter has one input of a regulating amplifier (RV) coupled to the junction between a pair of similar resistances (R',R''), connected in series across the driver outputs (a',a''), its other input supplied with a reference voltage (Uref), its output connected to the control input of the current source transistor.
