摘要： A circuit includes a multiplier circuit including a mixer configured to multiply a first differential input signal and a second differential input signal. The mixer includes a plurality of transistors including control terminals. The control terminals of the plurality of transistors receive a bias signal and the first differential input signal. A bias circuit is configured to generate the bias signal. The bias signal generated by the bias circuit is based on a voltage threshold of one of the plurality of transistors and a product of constant reference current and a bias resistance.

摘要： An apparatus comprises an amplifier and a pre-distortion circuit coupled to an input of the amplifier. A saturation value of an input signal corresponds to a maximum output power of an output signal of the amplifier. An input target value of the input signal is determined according to the saturation value. The input target value is determined by subtracting an offset from the saturation value or by multiplying a ratio by the saturation value. An average value or an RMS value of the input signal is controlled to be substantially equal to the input target value. A method comprises determining an input target value according to a saturation value, and controlling an input signal according to the input target value.

摘要： A transformer includes a first loops and second loops. The first loops include a first set of input terminals. The first loops include at least three loops that are conductively coupled to each other in series by first crossovers. The second loops include a first set of output terminals. The second loops include at least three loops that are conductively coupled to each other in series by second crossovers. Each of the second conductive loops is inductively coupled to and nested within a respective one of the first conductive loops.
