A novel 1 µW super-regenerative receiver with reduced spurious emissions and improved co-channel interferer tolerance

This paper introduces a novel approach for ultra-low-power radio receivers based on Armstrong's super-regenerative architecture. With a power consumption of 1 μW or less the receiver presents a big improvement to the state-of-the-art of 400 μW. In consequence, low maintenance wireless networks are much more feasible. Receiver sensitivity is measured -90 dBm. Spurious emissions from the oscillator are suppressed below -100 dBm, such that the receiver is suitable for wireless sensor networks with high nodal density. Dynamic co-channel interferers are tolerated instantaneously by means of parallel processing and forward error correction
