A mixer-first receiver with enhanced selectivity and high dynamic range is proposed, targeting to remove SAW-filters in mobile phones and cover all frequency bands up to 6 GHz. Capacitive negative feedback across the baseband amplifier serves as a blocker bypassing path, while an extra capacitive positive feedback path offers further blocker rejection. This combination of feedback paths synthesizes a complex pole pair at the input of the baseband amplifier, which is up-converted to the RF port to obtain steeper RF-bandpass filter roll-off and reduced distortion. This paper explains the circuit principle and analyzes receiver performance. A prototype chip fabricated in 45nm Partially Depleted SOI technology achieves high out-of-band linearity (IIP3=39 dBm, IIP2=88 dB) combined with sub-3 dB noise figure. Desensitization due to a 0-dBm blocker is only 2.2 dB at 1.4 GHz.

“…On the other hand linearity is significantly worse than in passive-first receivers, although hybrid approaches are also possible, see e.g. [25,58]. Overall, significant power consumption savings are certainly possible, as the N-path filter switches can be much smaller than in a 50ohm environment, see for instance the power comparison in [59].…”

Abstract-To realize a Software Defined Radio covering the mainstream 0.5-6 GHz wireless communication bands, new SAW-less radio receiver architectures are being explored which realize selectivity in a more flexible and programmable fashion. N-path filters and mixer-first receivers can offer high-linearity high-Q RF-filtering around a center frequency defined by a digital clock, which offers the desired flexible programmability. This paper reviews recent research on N-path filters and mixerfirst receivers, identifies advances in performance analysis, circuit performance and applications.
