UWB CMOS Monocycle Pulse Generator
IEEE Transactions on Circuits and Systems I: Regular Papers, 2010Co-Authors: F. Zito, Domenico Pepe, Domenico ZitoAbstract:A low-complexity fully integrated ultrawideband (UWB) monocycle Pulse Generator realized in 90-nm CMOS technology by ST-Microelectronics is presented. The circuit provides a monocycle Pulse when activated by a negative edge of an external trigger signal provided by a microcontroller by exploiting the operating principle of nonlinear waveform shapers. This Pulse Generator represents a building block of an innovative wearable system-on-chip UWB radar on silicon for cardiopulmonary monitoring. On-chip measurements show that the Pulse Generator provides monocycle Pulses with a duration time equal to 380 ps and a peak-to-peak amplitude of 660 mV (including the losses of the microprobes, cables, and electrostatic-discharge-protected pads), which are in very good agreement with the postlayout simulations. The power consumption is 19.8 mW from a 1.2-V power supply.

single chip cmos Pulse Generator for uwb systems
IEEE Journal of Solid-state Circuits, 2006Co-Authors: L Smaini, C Tinella, D Helal, C Stoecklin, L Chabert, C Devaucelle, R Cattenoz, N Rinaldi, Didier BelotAbstract:This paper presents a single-chip Pulse Generator developed for Ultra Wide Band (UWB) wireless communication systems based on imPulse radio technology. The chip has been integrated in a CMOS 130-nm technology with a single supply voltage of 1.2 V. The basic concept is to combine different delayed edges in order to form a very short duration "logical" Pulse, and then filter it, so as to obtain an UWB Pulse. It is possible to vary the output Pulse shape, and thus the corresponding spectrum, just by acting on the delayed edge combination. Furthermore, the Pulse Generator supports both position modulation (2-PPM) and polarity modulation (BPSK modulation) in order to convey data through the air. Its power consumption remains less than 10 mW for a raw data rate of up to 160 Mb/s. Spectral and temporal measurements of the single-chip Pulse Generator are presented with an illustration of the modulation effects on the power spectral density (PSD)

European Solid-State Circuits Conference, 2005Co-Authors: L Smaini, C Tinella, D Helal, C Stoecklin, L Chabert, C Devaucelle, R Cattenoz, Didier BelotAbstract:This paper describes the integration in a CMOS 130 nm technology of an ultra wide band (UWB) Pulse Generator. The implemented Generator controls the output Pulse shape, and thus the corresponding spectrum. Furthermore, the Pulse Generator supports both position modulation (2-PPM) and polarity modulation (BPSK) and draws 5 mA from 1.2 V. Spectral and temporal laboratory measurements of the single-chip Pulse Generator are presented.
