RECEPTION CIRCUIT AND SMART CARD INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240330613 titled 'RECEPTION CIRCUIT AND SMART CARD INCLUDING THE SAME
The present disclosure involves systems and devices with reception circuits for communication between smart cards and card readers. In some embodiments, a reception circuit of a smart card includes a first circuit and a second circuit. The first circuit receives a wireless signal with a pause and converts it into a clock signal. The second circuit charges a node based on the clock signal's logic level, compares the node's voltage with a reference voltage, and outputs a synchronization signal indicating the start of the pause in the wireless signal.
