A SiGe HBT low-power pulse generator for impulse radio ultra-wide band applications
In this paper a compact ultra-wide band (UWB) pulse generator using SiGe HBT technology is presented. The proposed circuit uses a simple circuitry to generate a current spike on chip, which in turn triggers an under-damped ...
A highly compact SiGe HBT differential LNA for 3.1 - 10.6 GHz ultra-wideband applications
A fully differential low noise amplifier (LNA) using SiGe HBT technology for ultra-wide band applications is presented. Measured results show the maximum power gain of 19.9 dB with a variation of 1.8 dB within the entire ...
Impulse generator targeting the European UWB mask
This paper presents a monolithic impulse generator IC targeting the spectral mask for ultra-wideband applications allocated in the European Union. The multicycle impulse is based on a spike triggered resonant circuit and ...
Multi-user capability of a FM IR-UWB system
A biphase modulator circuit for impulse radio-UWB applications
This letter presents a circuit to provide binary phase shift keying to ultra-wideband (UWB) impulse transmitters. The circuit is based on a Gilbert-cell multiplier and uses active on-chip balun and unbalanced-to-balanced ...
FM over impulse radio UWB
Recent regulatory action provided access to large chunks of spectrum for low spectral power density ultra-wideband communication and sensing devices, yet use of this spectrum currently lags behind expectations. The authors ...
IR-UWB radar demonstrator for ultra-fine movement detection and vital-sign monitoring
In this paper an impulse-radio ultra-wideband (IR-UWB) hardware demonstrator is presented, which can be used as a radar sensor for highly precise object tracking and breath-rate sensing. The hardware consists of an impulse ...
Si/SiGe HBT UWB impulse generators with sleep-mode targeting the FCC masks
In this paper two UWB impulse generator ICs are presented, targeting the FCC ultra-wideband spectral masks for indoor and outdoor communications. For the generation of the impulse an underdamped RLC resonance circuit is ...
Beam steerable IR-UWB antenna array with FCC-compliant impulse generators
A novel method for beam steering with an active ultra-wideband antenna array is presented for impulse-radio ultra-wideband. The antenna array consists of four planar Vivaldi antennas in a collinear arrangement with an ...
Si/SiGe HBT UWB impulse generator tunable to FCC, ECC and Japanese spectral masks
In this paper a fully integrated, low power and differential ultra-wide band (UWB) impulse generator is presented. The proposed circuit uses an on-chip generated current spike to shortly switch on an LC oscillator. The ...
