Title: | New design of low power, 100 Mb-s IR-UWB pulse generator in 0.18 μm CMOS technology | Authors: | Radić, Jelena Đugova, Alena Nađ, Laslo Videnović-Mišić, Mirjana |
Issue Date: | 1-Dec-2013 | Journal: | Microelectronics Journal | Abstract: | A new method of impulse radio ultra-wideband (IR-UWB) pulse generation, with advantage of providing a "notch" like representation of pulse in the spectrum domain for particular control parameters values, is investigated in this paper. Low power pulse generator is composed of a glitch generator, a switched oscillator, a two-stage buffer and a pulse shaping filter. The proposed architecture, designed in UMC 0.18 μm CMOS technology, can operate in a single band from 3.3 GHz to 9.3 GHz or in a double, lower and higher UWB band (from 3 GHz to 9.15 GHz), suppressing frequencies in the WLAN band. Both spectrums fully comply with the corresponding FCC spectral mask, while the pulse generator regime and the spectrum range are determined by control signal values. Post-layout simulation results showed a pulse width of 0.5 ns, and a peak-to-peak amplitude of 211 mV for one band spectrum. The average power consumption is 0.89 mW corresponding to the energy consumption of 8.9 pJ/pulse for 100 MHz pulse repetition rate (PRF). The pulse duration is 1 ns and peak-to-peak amplitude is 202 mV in the case of the WLAN frequency band suppression. The total chip area is 0.31 mm2. The pulse generator has been evaluated for the best performance supporting the on-off keying (OOK) modulation. © 2013 Elsevier Ltd. | URI: | https://open.uns.ac.rs/handle/123456789/8512 | ISSN: | 00262692 | DOI: | 10.1016/j.mejo.2013.08.007 |
