“…where v n cycle 6 0:1v o cycle , can be regarded as the pulse end point. Equation (2) proves that the number n cycle of output pulses can be controllable by ˇ; and thus the tunable R can control the pulse width for ˇD 1=2CR. Figure 5 shows that the pulse decay speed or the pulse amplitude can be continuously variable at different ˛and ˇ.…”

This paper presents a novel, fully integrated transmitter for 3-5 GHz pulsed UWB. The BPSK modulation transmitter has been implemented in SMIC CMOS 0.13 m technology with a 1.2-V supply voltage and a die size of 0.8 0.95 mm 2 . This transmitter is based on the impulse response filter method, which uses a tunable R paralleled with a LC frequency selection network to realize continuously adjustable pulse parameters, including bandwidth, width and amplitude. Due to the extremely low duty of the pulsed UWB, a proposed output buffer is employed to save power consumption significantly. Finally, measurement results show that the transmitter consumes only 16.3 pJ/pulse to achieve a pulse repetition rate of 100 Mb/s. Generated pulses strictly comply with the FCC spectral mask. The continuously variable pulse width is from 900 to 1.5 ns and the amplitude with the minimum 178 mVpp and the maximum 432 mVpp can be achieved.

A non-coherent receiver for impulse radio ultra-wide band (IR-UWB) is presented. The proposed receiver front-end consists of a high gain LNA, a high frequency detector and an intermediate frequency (IF) amplifier to amplify the recovered signal and drive an external test instrument. To meet the requirements of high gain and a low noise figure (NF) under moderate power consumption for the LNA, capacitor cross coupled (CCC) and current reuse techniques were adopted. The detector consists of a squarer and an integrator. The overall circuit consumes 41.2 mA current with a supply voltage of 1.8 V at a 400 MHz pulse rate. The resulting energy efficiency is 0.19 nJ/pulse. A chip prototype is implemented in 0.18-m CMOS. The die area is 2.1 1.4 mm 2 and the active area is 1.7 0.98 mm 2 .

“…On the one hand, although OFDM-UWB can provide a reliable broadband solution, it does so at the expense of circuit complexity and energy consumption due to the need for intensive digital signal processing [11]. The IR-UWB system, on the other hand, has been shown to be accommodated at low power consumption and provides simple transceiver topologies that can be readily integrated on a minimal chip area due to its intrinsically cyclical nature [12,13]. The objective of this research work is to design an innovative solution for the receiver part of a wireless sensor node device that maximizes the autonomy in a WBAN.…”

A double balanced passive mixer-based receiver operating in the 3-5 GHz UWB for medical applications is described in this paper. The receiver front-end circuit is composed of an inductorless low noise amplifier (LNA) followed by a fully differential voltage-driven double-balanced passive mixer. A duty cycle of 25% was chosen to eliminate overlap between LO signals, thereby improving receiver linearity. The LNA realizes a gain of 25.3 dB and a noise figure of 2.9 dB. The proposed receiver achieves an IIP3 of 3.14 dBm, an IIP2 of 17.5 dBm and an input return loss (S11) below -12.5dB. Designed in 0.18μm CMOS technology, the proposed mixer consumes 0.72pW from a 1.8V power supply. The designed receiver demonstrated a good ports isolation performance with LO_IF isolation of 60dB and RF_IF isolation of 78dB.
