  • Patent number: 10256723
    Abstract: A power factor correction (PFC) integrated circuit having a feed forward circuit. The feed forward circuit comprises a first current source, a second current source, and a third current source, a first bi-polar junction transistor (BJT), a second BJT, a third BJT, and a fourth BJT coupled together in a translinear cell, where the first current source is coupled to the first BJT, the second current source is coupled to the second BJT, and the third current source is coupled to the third BJT, a biasing network coupled to the first BJT and to the second BJT and configured to maintain equal collector-to-emitter voltage across the first BJT and the second BJT, where the feed forward circuit is configured to output a current based on a current of the first current source, a current of the third current source, and a current of the second current source.
