With the growing amount of wireless devices, interference robustness is a receiver specification of increasing importance. This paper presents a technique that improves both out-of-band compression and weakly non-linear distortion. It mitigates the effect of non-linearity in the baseband amplifier by preceding it by a cross-coupled passive filter. This(More)
Out-of-band noise (OBN) is troublesome in analog circuits that process the output of a noise-shaping audio DAC. It causes slewing in amplifiers and aliasing in sampling circuits like ADCs and class-D amplifiers. Non-linearity in these circuits also causes cross-modulation of the OBN into the audio band. These mechanisms lead to a higher noise level and more(More)
