Item A 30-100-GHz wideband sub-harmonic active mixer in 90-nm CMOS technology(IEEE Microwave Theory and Techniques Society, 2008-08-01) Jeng-Han Tsai; Hong-Yuan Yang; Tian-Wei Huang; Huei WangThis letter presents a 30-100 GHz wideband and compact fully integrated sub-harmonic Gilbert-cell mixer using 90 nm standard CMOS technology. The sub-harmonic pumped scheme with advantages of high port isolation and low local oscillation frequency operation is selected in millimeter-wave mixer design. A distributed transconductance stage and a high impedance compensation line are introduced to achieve the flatness of conversion gain over broad bandwidth. The CMOS sub-harmonic Gilbert-cell mixer exhibits -1.5 plusmn 1.5 dB measured conversion gain from 30 to 100 GHz with a compact chip size of 0.35 mm2. The OP1 dB of the mixer is -10.4 dBm and -9.6 dBm at 77 and 94 GHz, respectively. To the best of our knowledge, the monolithic microwave integrated circuit is the first CMOS Gilbert-cell mixer operating up to 100 GHz.Item Design and analysis of a 0.8-77.5-GHz ultra-broadband distributed drain mixer using 0.13-μm CMOS technology(IEEE Microwave Theory and Techniques Society, 2009-03-01) Hong-Yuan Yang; Jeng-Han Tsai; Chi-Hsueh Wang; Chin-Shen Lin; Wei-Heng Lin; Kun-You Lin; Tian-Wei Huang; Huei WangA compact and broadband 0.8-77.5-GHz passive distributed drain mixer using standard 0.13-mum CMOS technology is presented in this paper. To extend the operation bandwidth, a uniform distributed topology is utilized for wideband matching. This paper also analyzes the device size and number of stages for the bandwidth of the CMOS distributed drain mixer. To optimize the conversion gain performance of the CMOS drain mixer, a gate bias optimization method is proposed and successfully implemented in the mixer design. This mixer consumes zero dc power and exhibits a measured conversion loss of 5.5 plusmn1 dB from 0.8 to 77.5 GHz with a compact size of 0.67 0.58 mm2 . The output 1-dB compression point is -8.5 dBm at 20 GHz. To best of our knowledge, this monolithic microwave integrated circuit has the widest operation bandwidth among CMOS wideband mixers to date with good conversion efficiency and zero dc power consumption.Item 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 HuangA 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.
