“…Including some digital baseband, the 60 GHz transceiver [3] consumes 580 mW at 2 Gb/s data rate, which is not suitable for the smartphone-based applications. Compared to the work in [6,13] which are based on the UWB technology, this work achieves the highest data rate with the highest energy efficiency.…”

“…An array of digital power amplifier (DPA) cells is controlled by an array of selected digital phases which are generated by the baseband PLL. The proposed carrier-based plus digital pulse shaping (DPS) architecture can thus benefit from the advantages of the two ones in work [12,13]. The pulse center frequency tunability as well as the DPS flexibility is obtained.…”

Abstract-This paper describes a high data rate proximity transmitter design for high resolution smartphone-mirrored display applications. A 2 Gb/s transmitter is designed with a low transmission power of -70 dBm/MHz and a wide bandwidth of nearly 3 GHz. A digital pre-correction method is employed in the transmitter to mitigate the inter-symbol interference problem. A carrier-based digital pulse shaping and a reconfigurable digital envelope generation methods are employed for robust operation by utilizing 20 phases from a 2 GHz phaselocked loop. A 6.5-9.5 GHz transmitter implemented in 65 nm CMOS achieves the maximum data rate of 2 Gb/s, consuming only 7.6 mW from a 1 V supply.

“…It consists of an LC digitally-controlled oscillator (DCO), a digital pulse envelop (DPE) generator, a 2GHz phase-locked loop (PLL) with a ring voltage-controlled oscillator (VCO), an output buffer. For pulse shaping, a carrier-based digital pulse shaping (DPS) scheme is used for robust operation compared to the all-digital [6] or the carrierbased analog shaping [7] methods. Since the noncoherent receiver does not require an accurate carrier frequency control, an open-loop DCO is implemented.…”

“…Correlation-based energy detection is of high sensitivity at the cost of complex digital signal processing hardware [7,8,9,10]. Coarse energy detection is mostly achieved by squarer, which converts signal into DC [11,12]. However, its major goal is to detect the existence of a certain signal, rather than quantify magnitude of the interested signal.…”

To meet the stringent spectral mask requirement of IEEE 802.15.6, a novel spectral shaping buffer and a new automatic calibration are proposed in this paper. By introducing a floating current into buffer, second order intermodulation product (IM2) is cancelled at output. To calibrate buffer, analog signal processing methods for average power extraction of residual IM2 and accurate quantization are presented, along with error-tolerant decision making logic. A sample human body communication (HBC) transmitter is designed in 0.13 µm CMOS process. Simulation results show spectral mask is suppressed below −120 dBr, satisfying the IEEE 802.15.6 standard specification.
