“…A DAC-based UWB pulse generator, however, requires Nyquist rate sampling, e.g., at least 10 GSample/s for the low band, and over 20 GSample/s for the high band. The high sampling rate poses a challenge not only for the DAC, but also for generating the input digital data stream, which usually requires power-hungry high speed digital circuits, such as current-mode logic, using advanced technologies such as SiGe BiCMOS [19]. Therefore, it is imperative to leverage some analog and RF techniques to reduce the sampling rate and power requirement in a waveform synthesis architecture.…”

Abstract-A new circuit technique, the distributed waveform generator (DWG), is proposed for low-power ultra-wideband pulse generation, shaping and modulation. It time-interleaves multiple impulse generators, and uses distributed circuit techniques to combine generated wideband impulses. Built-in pulse shaping can be realized by programming the delay and amplitude of each impulse similar to an FIR filter. Pulse modulation schemes such as on-off keying (OOK) and pulse position modulation (PPM) can be easily applied in this architecture. Two DWG circuit prototypes were implemented in a standard 0.18 m digital CMOS technology to demonstrate its advantages. A 10-tap, 10 GSample/s, single-polarity DWG prototype achieves a pulse rate of 1 GHz while consuming 50 mW, and demonstrates OOK modulation using 16 Mb/s PRBS data. A 10-tap, 10 GSample/s, dual-polarity DWG prototype was developed to generate UWB pulses compliant with the transmit power emission mask. Based on the latter DWG design, a reconfigurable impulse radio UWB (IR-UWB) transmitter prototype was implemented. The transmitter's pulse rate can be varied from 16 MHz range up to 2.5 GHz. The bandwidth of generated UWB pulses is also variable, and was measured up to 6 GHz ( 10 dB bandwidth). Both OOK and PPM modulation schemes are successfully demonstrated using 32 Mb/s PRBS data. The IR-UWB transmitter achieves a measured energy efficiency of 45 pJ/pulse, independent of pulse rate.

“…The Digital to Analog Converter (DAC) with high sampling rate, medium resolution (6-8 Bits) are more and more required for high speed data links such as optical communication systems, radar communication systems or satellite communication systems. Another forthcoming and very advanced application of Digital to analog converters with a high-speed, less power consumption is 5G mobile communication systems [8]. A DAC Based on a Differentiating Arbitrary Waveform Generator Architecture for 5G Handset Transmitter is presented in [2].…”

A Low power 6-bit R-2R ladder Digital to Analog Converter is presented in this paper. Here the R-2 R network designed using resistors with only two values-R and 2xRand the switch is designed by using both NMOS and PMOS Transistors. This Digital to Analog Converters operated with low voltage, by applying dynamic threshold MOSFET (DTMOS) logic. This design achieved less INL and DNL which is 0.3 and 0.06 respectively. Power supply required to operate this device is only 1V with10GHzconversion rate. This design is implemented by using 0.18μm CMOS technology.

“…On the transmitter side, there are several approaches for IR-UWB pulse generation ( Fig.1): carrier-based up-conversion [6], [7], direct pulse generation [8], [9], waveform synthesis based on high speed digital-to-analog converters (DAC) [10]. Carrier-based up-conversion defeats one of the major advantages of IR-UWB (no carrier) and results in large circuit complexity and power consumption.…”

Abstract-Ultrafast pulse generation and detection are pivotal functions in ultra-wideband (UWB) impulse radios. This paper shows that digitally-assisted distributed circuit techniques provide an energy-efficient, reconfigurable solution for both functions, as demonstrated in two new circuits: a pulse generator that can generate reconfigurable pulse waveforms with subnanosecond time resolution, and a multi-GHz analog correlator that incorporates reconfigurable local template pulse generation. A UWB impulse radio was developed based on these new circuits with chip prototypes implemented in 0.18-µm standard digital CMOS. It was characterized using UWB antennas, and achieved an energy efficiency of 25-pJ/pulse for the transmitter and 190-pJ/pulse for the receiver at 250 MHz pulse rate in the measurement.
