“…The first inverter of the delay circuit (Fig. 6) employs a current-starved topology with symmetrical load (Mp3 and Mn3) to control the current over Mp4 and Mn4 [16,20,21]. This type of inverter performs a frequency adjustment through two current mirror circuits.…”

“…Table 5 compares the present work with related approaches, using as criteria technology node, voltage supply, design method, area, PRF, power consumption, modulation technique choice and degree of design Most of the approaches in the literature do not have adaptable PSD. While reference [21] reports the support to adaptive PSD in their approach, there is a dependency in that design between PRF and PSD values. These can be independently chosen in the design described here.…”

The current state of the telecommunications market exhibits a high potential to absorb efficient innovations in wireless connectivity, especially those that can be applied to the Internet of Things and similar domains. Contributing in that direction, this paper describes the design and implementation of a fully differential impulse-radio ultra-wideband (IR-UWB) transmitter using pulse-amplitude modulation, with an adaptive power spectrum density (PSD). The architecture can produce up to eight differential monocycles per clock pulse at its output. The number of monocycles controls the bandwidth (thus the PSD) in the mask of IR-UWB technologies, allowing adaptation to multiple standards. The complete transmitter has four main blocks: (a) a pulse generator, comprising two pulse generating circuit groups, to modulate and create a rectangular waveform; (b) an active balun with two amplifiers, to generate differential signals; (c) a digital demultiplexer, to alternate data to the pulse generating circuit groups; (d) a binary-to-thermometer decoder, to control the amount of generated monocycles per pulse. Simulations demonstrate an output pulse amplitude of 120 mV for the high logic level and of 70 mV for the low logic level, both at a 100 MHz Pulse Repetition Frequency. This produces a mean pulse duration of 277 ps, a mean central frequency of 3.8 GHz, and a mean power consumption 6.7 mW. The transmitter takes the form of an intellectual property core in a 130 nm CMOS technology. The complete transmitter area is 0.067 mm 2 , without I/O pads. The outcomes suggest that the proposed circuit can narrow or widen the output signal bandwidth, providing adaptability to different emission requirements.

“…Recently reported IR-UWB TXs generate appropriately shaped signal based on (a) delay-based pulse or edge recombination [6,9,12,[24][25][26][27][28], (b) the duty-cycled or switched oscillator [3,14,15,29,30], (c) up-conversion using mixer and frequency synthesis [7,16,18,19,[21][22][23]31], and (d) on-chip filtering solutions [2,32,33]. Although all-digital solutions based on pulse or edge recombination avoid using a mixer or/and an oscillator to enable low power consumption and faster settling time, they still require a pulse shaper (usually band-pass or high-pass filter) to reduce the low-frequency spectrum components and have difficulties in summing or adjusting overlapped delayed pulses demanding complex calibration and programmability features.…”

An impulse radio ultra-wideband (IR-UWB) transmitter (TX) consuming ultra-low power is presented. The lowcomplexity topology features control of the power spectral density (PSD) and central frequency for a broad range of applications. The PSD and frequency adjustment are accomplished by employing a tunable pulse generator and an adjustable driver. The IR-UWB TX suitable for on-off keying coding is fabricated in a low-cost 180 nm UMC CMOS technology and occupies the total die area of 0.63 mm 2. The measurement results show the transmitter output swing of 320 mVpp (peak-topeak amplitude) with the pulse duration of 0.6 ns, and the spectrum covering the frequency range from 3 to 7.5 GHz. The total DC power consumption is 1 mW resulting in energy consumption of 5 pJ/pulse at 200 MHz data rate.

“…Recently notable integrated configurations have been proposed to add a certain amount of flexibility in these solutions. In [19], a CMOS pulse generator with flexibility in terms of amplitude is proposed. To modulate the pulse amplitude, the pulse generator exploits the variation of the duty cycle of the input signal that defines the bit pattern.…”

This paper presents a fully tunable baseband ultrawideband (UWB) pulse generator, realized with commercial offthe-shelf components (COTS). It is made of high speed logic gates and comparators, and it is compliant with current mode logic (CML) digital standard. The pulse emitted power and bandwidth are tunable with pulse-width and amplitude variation, which shows high flexibility. This advantage simplifies the design of the downstream shaping network, as so to be compliant with international regulations. A differential output with very low jitter, and high pulse repetition frequency (PRF) is demonstrated.
