Methods, algorithms, architectures, circuits, and/or systems for managing POR-less integrated circuits are disclosed. The method of validating code from a wireless device can include: (i) broadcasting a signal from a reader to the wireless device, (ii) reading a code transmitted, re-radiated, and/or backscattered from the wireless device, the code having a predetermined quality, characteristic, and/or property, (iii) comparing the code to a reference quality, characteristic, and/or property, and (iv) validating the code when the predetermined quality, characteristic, and/or property matches the reference quality, characteristic, and/or property. Embodiments of the present invention can advantageously provide a reliable approach for validating integrated circuits that do not incorporate a POR circuit, and which therefore may transmit spurious bits of data upon being energized. In addition, embodiments of the present invention advantageously allow an Aloha-type anti-collision function to be implemented in a reader based on POR-less integrated circuits. |
