title = "Online Self-Adaptive Estimation and Compensation Design for DC Voltage Offset, Frequency-Independent, and Frequency-Dependent IQ Mismatch in Sub-THz Digital Baseband Transceiver",
abstract = "This paper presents a baseband transceiver architecture working at Sub-THz based on IEEE 802.15.3d. We propose an online self-adaptive compensator (OSAC) to deal with DC voltage offset (DCVO), frequency-independent IQ (FIIQ) mismatch, and frequency-dependent IQ (FDIQ) mismatch. For DCVO compensation, the residual DCVO in I/Q branch is improved from 75 mV / 75 mV to 0.0027 mV / 0.0024 mV. For FIIQ mismatch, the image rejection ratio (IMRR) is improved from 12.80 dB to 55.09 dB. For FDIQ mismatch, the IMRR can be improved from 26.02 dB to 73.38 dB. The hardware implementation of OSAC is operated at 3.52 GHz with the TSMC 16-nm FinFET CMOS process to achieve the data rate of 14.02 Gbps. The core area and power consumption of OSAC are 12769 μm2 and 84.7 mW, respectively.",
