  • Patent number: 10153760
    Abstract: A circuit architecture and process that provides for a dual-mode methodology for an RF integrated circuit (IC) switch circuit that allows switching between a direct mapping configuration and a fully decoded mapping configuration, and further provides for changing either mapping configuration after fabrication. A control word is selectively compared to a programmed map register value so that, in a first mode, only one bit position of a control word matches a decoded programmed map bit pattern, and in a second mode, all bits of a control word match a corresponding programmed map bit pattern. Because the map registers can be programmed at least once after IC fabrication, the exact mapping required for a particular application can be determined post fabrication. Further, the first mode of operation is often beneficial during testing because multiple RF signal paths can be turned on at the same time and thus tested in parallel.
