摘要：
The present invention provides for a circuit with slicing wherein a gain asymmetry variation is decreased across the plurality of mixer slices. In one or more embodiments, a calibration unit can be provided to determine the characteristics of gain asymmetry variation; and a digital compensation unit can be provided to adjust the gain of the circuit over frequency.
