A Millimeter Wave Digital CMOS Baseband Transceiver for Wireless LAN Applications

In this paper, we introduce a 10 Gbps digital baseband transceiver with 1V supply voltage, 16-QAM, 3/4 code rate single carrier mode using 28 nm CMOS process to do the implementation. In millimeter wave communications, well-defined standard, IEEE 802.11ad is referenced for our system design and simulation. We target at modified chip rate 2.5 GHz with 4 times parallelism hardware at clock rate 625 MHz. The overall transceiver architecture design with hardware implementation considerations will be proposed. With the smart shared memory allocation, we can reduce 31% of the total amount. According to the referenced specifications, we achieve the required bit error rate 3 × 10 ^-7 before SNR 18.5 dB. After the system algorithm design, we implement the hardware with the core area 2.92 mm ² with measured power 1.8 Watt for baseband transceiver chip. The performance of energy per bit is 0.023 nJ and 0.211 nJ per bit for Tx and Rx, including ADC/DAC.
