Abstract
In this letter, an ultrabroadband D-band wireless front-end receiver (RX) in 45-nm CMOS SOI is proposed. It achieves a noise figure of 8 dB, a gain of 16 dB, a 3-dB bandwidth of 25 GHz, and occupies a compact area of 2 mm2. To the best of our knowledge, for the first time, the required millimeter-wave local oscillator signal is generated on-chip. Furthermore, 108-Gb/s data-rate is demonstrated by receiving and demodulating a signal composed of $10\times 2.16$ GHz channels with −40-dBm average power and 64-QAM modulation. With a consumption of 200 mW from a 1-V voltage supply, the proposed RX achieves an energy efficiency of 1.8 pJ/bit.
