This paper describes a monolithic integrated non-coherent receiver intended for impulse radio (IR) Ultra-wide band (UWB) applications including indoor communication and indoor localization. The receiver operates in the higher UWB band centered at 7.68 GHz and it is optimized for a pulse bandwidth of about 1.5 GHz. The overall gain of the receiver amplification chain can be set up to 56 dB in 16 steps via a digital 4-bit interface. A dedicated ldquoleading edgerdquo-detector supports precise indoor localization in conjunction with an appropriate UWB transmitter. A fast comparator indicates the exceeding received signal beyond a threshold set by an internal digital-to-analogue converter (DAC). The circuit was fabricated in 0.25 mum SiGe:C BiCMOS technology.
