A 70-GHz Transformer-Peaking Broadband Amplifier in 0.13-μm CMOS Technology
نویسندگان
چکیده
A 70-GHz broadband amplifier is realized in a 0.13-μm CMOS technology. By using five cascaded commonsource stages with the proposed asymmetric transformer peaking technique, the measured bandwidth and gain can reach 70.6 GHz and 10.3 dB respectively under a power consumption (PDC) of 79.5 mW. With miniaturized transformer design, the core area of the circuit is only ~ 0.05 mm. Compared with the state-of-the-art CMOS broadband amplifiers, this work achieves the highest gain-bandwidth product (GBW) of 231 GHz and also the highest GBW/PDC of 2.9 GHz/mW. Index Terms — Broadband amplifier, CMOS, common-source stage, gain-bandwidth product, transformer peaking.
