A 3.54 nJ/bit receiver front-end for 3-5 GHz impulse radio UWB is proposed in this paper. Noncoherent receiver architecture enables the implementation of a low cost, low power and low complexity receiver. Current-reuse technique is employed in the LNA to reduce the power consumption while achieving high gain. The designed LNA can achieve 40 dB voltage gain and the receiver front-end can achieve a...
This paper presents a dual-channel timed array transmitter for impulse radio ultra wide band wireless communication system. The transmitter can generate UWB pulses in two separate transmitter paths with tunable path delay difference of 0˜250 ps to achieve beamforming capability. Through injection locking with 800 MHz input reference, the generated UWB pulse centers at 4 GHz and covers 3˜5 GHz band...
A ultra-wideband low noise amplifier (LNA) with integrated notch filter for interference rejection is designed using 0.18-mum CMOS technology. The three-stage LNA employs a current reuse structure to reduce the power consumption and a serial LC circuit with Q-enhancement circuit to produce band rejection in the 5-6 GHz frequency band. The load tank optimization for the current reuse stage is discussed...
