Abstract
In one embodiment, a circuit comprises a first pair of elements, a second pair of elements, a combiner, and a signal output. Each element in the first and second pair of elements comprises an amplitude-control input for receiving an amplitude-control bit, a phase-control input for receiving a phase-control bit, a signal input for receiving an input signal, a modulator for producing an output signal based on the amplitude-control bit, the phase-control bit, and the input signal, and an signal output for transmitting the output signal to the combiner. The combiner combines the two output signals from the first and second pair of elements to produce an output signal for the circuit to be transmitted by the signal output of the circuit.
