A 42-GHz transmitter linearization using pre-distortion IF amplifier
(Wiley-Blackwell, 2009-06-01) Jeng-Han Tsai
This article presents a millimeter-wave (MMW) transmitter linearization using predistortion IF amplifier. The predistortion IF amplifier was designed in 0.18-μm CMOS technology at 2.4 GHz. It can provide predistortion function at IF port to linearize the whole MMW transmitter. The 42-GHz transmitter module is custom design. After linearization, 8 dB ACPR improvement of the 42-GHz MMW transmitter module can be achieved. The linear output power of the 42-GHz transmitter module has been increased 2 dBm for the same linearity requirements
A 60-GHz CMOS power amplifier with built-in pre-distortion linearizer
(Institute of Electrical and Electronics Engineers (IEEE), 2011-12-01) Jeng-Han Tsai; Chung-Han Wu; Hong-Yuan Yang; Tian-Wei Huang
A built-in pre-distortion linearizer using cold-mode MOSFET with forward body bias is presented for 60 GHz CMOS PA linearization on 90 nm CMOS LP process. The power ampli- ﬁer (PA) achieves a of 10.72 dBm and of 7.3 dBm from 1.2 V supply. After linearization, the has been doubled from 7.3 to 10.2 dBm and the operating PAE at consequently improves from 5.4% to 10.8%. The optimum improvement of the IMD3 is 25 dB.
