发明名称 System and Method for a Cancelation Circuit
摘要 In accordance with an embodiment, a cancelation circuit includes a current mirror and a low pass filter. The current mirror includes an input terminal configured to accept an input current comprising a first noise signal, a first mirrored output and a second mirrored output. The low pass filter includes an input coupled to the first mirrored output and an output coupled to the second mirrored output. A sum of a current from the second mirrored output and a current of from the output of the low pass filter includes a phase-inverted version of the first noise signal.
