Abstract
A low-power wake-up receiver. The receiver includes a transformer/filter resonating at a pre-selected frequency to realize passive RF voltage gain. A pseudo-balun envelope detector is coupled to an output of the transformer filter. A comparator or other quantizer is coupled to an output of the active pseudo-balun envelope detector (ED) for comparing the ED output to a comparison threshold voltage. The pseudo-balun envelop detector can be an active detector. The pseudo-balun detector can also be a passive detector.
