29-to-65-GHz CMOS Amplifier with Tunable Frequency Response

In the 300-GHz band, a very wide bandwidth of up to 44GHz is available for wireless communications. This paper presents a frequency-response tunable CMOS IF amplifier, intended for 300-GHz wireless communications. It could be used for frequency-domain equalization at IF. The amplifier was fabricated using a 40-nm CMOS process. 3-dB bandwidth of 36GHz and power gain of 27.3dB are obtained at a power consumption of 144mW.
