In a direct-conversion wireless receiver the baseband filter should be able to handle large blockers, resulting in a very challenging spurious free dynamic range (SFDR) requirement. In particular, the noise added in-band trades off with the linearity required to handle close out-of-band interferers [1]. Since the integrated noise generally is proportional(More)
A novel class of filters (called pipe filters) that features in-band noise reduction is presented and a current mode biquad cell based on cross-connected cascoded devices is introduced. The presented solution gives in-band high-pass noise shaping and passive pre-filtering of out-of-band blockers. This results in both low in-band noise and high out-of-band(More)
