Abstract

Although millimeter wave (mmWave) wireless communication has the advantages of huge bandwidth, narrow beam and high transmission quality, it also suffers from severe signal attenuation caused by atmospheric absorption and short distance transmission. Therefore, the equalization techniques are normally required in mmWave links. In this paper, a continuous time linear equalization (CTLE) with variable gain for mmWave receiver was designed in IHP 130 nm SiGe BiCMOS process. The CTLE circuit incorporates an active equalizer with negative capacitance converter and a variable gain amplifier (VGA). The negative capacitance structure was used to increase the peaking gain at Nyquist frequency to compensate for the high frequency loss, and the VGA provides an adjustable low frequency gain. The simulation results demonstrate that the tuning capabilities of 12 dB and 5 dB can be respectively achieved for low frequency and high frequency, and the equalization performance is verified for two different channels at 25 Gb/s NRZ data streams.
