  • Integrated current replicator and method of operating the same
    Patent number: 10020739
    Abstract: An integrated current replicator includes a first current sense resistor configured to sense a first input current to a power converter during a primary portion of a duty cycle and a first transconductance amplifier configured produce a first voltage at a common circuit node proportional to the first input current during the primary portion of the duty cycle. The integrated current replicator includes a second current sense resistor configured to sense a second input current to the power converter during a complementary portion of the duty cycle and a second transconductance amplifier configured produce a second voltage at the common circuit node proportional to the second input current during the complementary portion of the duty cycle. The integrated current replicator includes an amplifier configured to produce a voltage replicating the first input current and the second input current from the first voltage and the second voltage.
