    Abstract: A method of transferring data between a first electrical component (16) and a second electrical component (18), which are both coupled to a common oscillator (62) that oscillates at a first frequency, the first electrical component (16) generating a first bit stream having a second frequency that is a fraction of the first frequency and having a first number of bits, generating an indicator signal having a third frequency that is a fraction of the first frequency and that is indicative of a type of data represented by the first bit stream, and coupling the first bit stream and the indicator signal to the second electrical component. The second electrical component (18) sampling the first bit stream and the indicator signal at a fourth frequency that is substantially identical to the second frequency, thereby recovering the first bit stream generated by the first electrical component (16) and determining the type of data contained in the first bit stream.

    Abstract: A transmitter (107) includes amplifying circuitry (203) and control circuitry (215, 217, 219) for biasing the amplifying circuitry (203) so that it operates closer to saturation with increased efficiency. The gate voltage signal (213), which provides a gate bias, is coupled to the amplifying circuitry (203) and is dynamically varied by the processor circuitry (219) in response to the value of the amplifier control voltage (211) coupled to the amplifying circuitry (203). The amplifier control voltage (211), which has a value for maintaining the output power of the amplifying circuitry (203) at a constant, is produced by the integrating circuitry (217) in response to a comparison of the detected power output signal (216) produced by the detecting circuitry (215) and the power output control signal (218) produced by the processor circuitry (219). Efficiency is realized by dynamically varying the gate voltage signal (213) to its largest magnitude so that the amplifying circuitry (203) may operate as close to saturation as possible while still maintaining a constant output power.
