This paper surveys the research on frequency modulated ultrawideband (FM-UWB) transceivers. FM-UWB system uses low modulation index digital FSK followed by high modulation index analog FM to generate a constant envelope UWB signal with a flat power spectral density and steep spectral roll-off. FM-UWB can be seen as an analog implementation of a spread spectrum system with spreading gain equal to the modulation index. FM-UWB system is suitable for low data rate and short-range applications. The advantages of FM-UWB system such as low power consumption, very low radiated power (−41.3 dBm/MHz), good coexistence with other existing wireless technologies, and robustness to interference and multipath making it suitable for Wireless Body Area Network (WBAN) in medical applications. General TermsUltra-wideband (UWB), UWB transceivers.

This work presents a novel fast switching low power low noise amplifier (LNA) for 6-10 GHz ultra wide band applications using 0.13µm CMOS process from STMicroelectronics. The LNA operates at 1.2V. It achieves a high differential voltage gain about 46 dB with 4.4dB noise figure and a power consumption of 24mW. Fast on and off power switching is achieved by using differential amplifiers with DC coupled eliminating the use of large capacitors that leads to long charging time constants. The output voltage is settled in 1.5 ns when the LNA is switched on and off. The circuit consumes only 32.4 µW of dc power when duty-cycled@100kbps allowing reducing the power consumption.

“…This way, practical inductor values leading to high SFR value and high Q factor can be chosen according to the LNA operating bandwidth. Once the values of inductors L 1 and L 2 are fixed, relations (1)(2)(3)(4)(5)(6)(7)(8)(9) give the input matching cell element values for a given power consumption and a given value of the degeneration inductance L S .…”

“…In the case of small fractional bandwidths the input matching cell relations are given by (1)(2)(3)(4)(5)(6)(7)(8)(9). Equation (7) can be approximated by (25) because J 3 must be chosen in order to be low in comparison to unity in the input matching cell design as mentioned above.…”

“…In addition a constant group delay is required in the signal bandwidth to maintain the signal integrity of the pulsed wideband signal. Wide band CMOS LNA have been designed by using several topologies: distributed amplifiers [1,2], feedback amplifiers [3][4][5], common gate [6][7][8], or LC ladder filters LNA [9]. Beside the others topologies, LC ladder filter LNA allow constant gain and group delay in a well controlled bandwidth.…”

The design and the implementation of Ultrawide-band (UWB) CMOS LC filter LNA for Ultra Wide Band carrier less Impulse Radio receivers is presented. Architectures for both single ended and differential ended LNA are proposed for small fractional bandwidths such as the ECC frequency band and for large fractional bandwidths such as FCC frequency band. Simple guidelines to achieve large voltage gain and low noise figure are given. The implementation in standard CMOS technologies in the context of integrated receivers is discussed and simple layout rules allowing reliable designs are proposed. Several LNA prototypes for different fractional bandwidths have been fabricated in a 0.13 lm CMOS technology. Measurement results agree well with the simulations.
