Abstract
Doppler-inspired methods for signal generation and frequency up-conversion are provided that are compatible with CMOS technology. In accordance with an embodiment, a circuit is provided that includes two input signals that can propagate on artificial transmission lines in opposite directions, resembling the relative movement of source and observer in Doppler frequency shift; and an output signal combiner. By controlling the characteristics of the transmission lines and the input signal frequencies, the harmonic generation of active devices is utilized and combined to provide the desired high-frequency component at the output.
