    摘要: A voltage scaling circuit includes a first critical path and an edge detection unit. The first critical path includes an input and an output. The edge detection unit includes a first input, a second input, a counter and a time-to-digital converter (TDC). The input of the first critical path is electrically connected to the first input of the edge detection unit, and the output of the critical path is electrically connected to the second input of the edge detection unit. The counter is configured to measure a duration between an active edge of a start signal on the first input of the edge detection unit and an active edge of a stop signal on the second input of the edge detection unit in a clock period basis. The TDC is configured to measure a beginning portion and an end portion of the duration.

    摘要: A semiconductor wafer includes a plurality of dies. Each of the plurality of dies includes a radio frequency identification (RFID) tag circuit and a coil. The RFID tag circuit includes a tag core, an RF front-end circuit, an ID decoder, a comparator and conductive line for a unique ID. The RF front-end circuit is configured to receive electromagnetic signals through the coil in each of the plurality of dies and to convert the received electromagnetic signals into commands. The ID decoder is configured to receive the commands and to generate an expect ID. The comparator is configured to compare the unique ID with the expect ID to generate a comparison result. The comparison result is arranged to decide if the tag core is configured to receive commands.
