N2 - Upcoming Internet-of-Things (IoT) applications require low-power multi-standard RF receiver (RX) front-ends. Interference rejection becomes increasingly important as ever more devices compete in the scarce 10w-GHz spectrum. Typically, low-power RXs do not possess very steep filtering [1]-[6]. On the other hand, very selective RXs - e.g. using analog FIR or Filtering-by-Aliasing [7] - have very high power consumption, not suitable for IoT applications. A recent Analog Finite-Impulse-Response (AFIR) filter [8] shows promising results to improve channel filtering. [8] uses a much lower FIR update rate than [7] to considerably reduce power consumption. This comes at the cost of a filter alias, but the inherent windowed integration sinc filtering mitigates this filter alias. Achieving low RX Noise Figure (NF), while improving selectivity is challenging at ultra-low power, where all blocks tend to contribute significantly to the total power consumption [1]-[6].
