    Abstract: A configurable 2-wire/3-wire serial communications interface (C23SCI), which includes start-of-sequence (SOS) detection circuitry and sequence processing circuitry, is disclosed. When the SOS detection circuitry is coupled to a 2-wire serial communications bus, the SOS detection circuitry detects an SOS of a received sequence based on a serial data signal and a serial clock signal. When the SOS detection circuitry is coupled to a 3-wire serial communications bus, the SOS detection circuitry detects the SOS of the received sequence based on a chip select (CS) signal. In response to detecting the SOS, the SOS detection circuitry provides an SOS detection signal to the sequence processing circuitry, which initiates processing of the received sequence using the serial data signal and the serial clock signal. The received sequence is associated with one of multiple serial communications protocols.

    Abstract: Radio frequency (RF) power amplifier (PA) circuitry, which transmits RF signals is disclosed. The RF PA circuitry includes a final stage, a final stage current digital-to-analog converter (IDAC), and a final stage temperature compensation circuit. A final stage current reference circuit may provide an uncompensated final stage reference current to the final stage temperature compensation circuit, which receives and temperature compensates the uncompensated final stage reference current to provide a final stage reference current. The final stage IDAC uses the final stage reference current in a digital-to-analog conversion to provide a final stage bias signal to bias the final stage. The temperature compensation provided by the final stage temperature compensation circuit is selectable.
