摘要: Systems and methods for canceling static dynamic DC offsets by combining a digital offset correction scheme with an analog scheme. A feedback-based provides different adjustment levels plurality of discrete gain states the operates in cancellation modes dependent on frame structure. collects control information levels. In addition, negative-feedback based switchable high pass filter has operation, where one mode operation includes all-pass filter.
