An architecture for supplying air to a high-pressure compressor of an auxiliary gas generator from a pressurized cabin of an aircraft, comprising: a load compressor rotationally driven by a common rotation shaft providing a mechanical coupling between the high-pressure compressor and a high-pressure turbine of the auxiliary gas generator and supplied by an outside air intake; a first regulation valve assembled at the outlet of the load compressor to control all or part of the air flow delivered by the load compressor; a second regulation valve assembled at the outlet of the pressurized cabin to control the air flow drawn from inside the pressurized cabin; a mixer receiving the outputs of the first and second regulation valves to add the air drawn from inside the pressurized cabin to all or part of the air delivered by the load compressor.
