• radio-frequency testing
• spectrum measurement

Our RF signal-quality measurement macro employs 1) a new window-shifting measurement technique that obtains the power of a high-frequency component on the basis of lower-frequency measurements, and 2) a new stair-like weighted addition technique that decreases error due to harmonic power, phase, and DC offset in measured signals. The macro occupies only 1/10 the area of conventional on-chip spectrum analyzers. Carrier power for 2.4 GHz-Tx was successfully measured with digital testers alone, with an error of only < 1 dB, and harmonic-emission exceeding FCC regulations (> - 20 dBm) was also successfully detected.
