“…However, there were more scopes to improve the performance of UWB transmitter. Some recent research (Lo et al, 2013;Radic et al, 2020;Bahrami et al, 2015;Notch et al, 2013) have designed UWB transmitter. The mentioned works has reduced the power consumption but there is huge scope of reducing the power by using different components as power consumption is one of the most important parameters for wireless medical devices.…”

The use of ultra-wideband (UWB) in target detection, radar and wireless connectivity, specifically in the medical world, has attracted a lot of attention. The concept that the IR-UWB system does not necessarily require carrier signals is one of its most appealing features. IR-UWB can transmit information using short Gaussian monocycle pulses. In light of these advantages, this paper proposes a novel UWB transmitter system which consists of UWB signal generating circuits and UWB antenna, which work together to create entire UWB transmitter. It is based on impulses and has a simple architecture with low power consumption. The proposed transmitter is realized in Cadence tools with 90nm CMOS technology and proposed UWB antenna is simulated using Advanced Design System (ADS) simulator software. In addition, the transmitter circuit and the antenna are co-simulated using ADS software. The illustrated UWB transmitter uses a low-power supply and generates pulse amplitude with pulse duration of for the Gaussian monocycle pulse. Due to its increased output voltage swing and reduced power consumption when comparing to other circuits, the proposed architecture is functional and suitable for use in short-range wireless networks and medical applications.

“…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.
