0.13 μm CMOS Cartesian loop transmitter IC with fast calibration and switching scheme from opened to closed loop |
Abstract | ||
|---|---|---|
A 0.13 mum CMOS Cartesian loop transmitter IC with calibration and loop setting scheme of less than 5 mus is fabricated in order to keep high efficiency in wide output power range. The proposed scheme adjusts amplitude, phase, loop gain by using TX modulated signal for fast loop setting. Adjacent channel power leakage ratio (ACPR) is improved by 18 dB. The transmitter IC without PA consumes 62 mA, in which feedback path consumes 22 mA. |
