Abstract

This paper presents for the first time the circuit parameter analysis of a digital multiband-UWB transceiver, encompassing a novel low-power sub-band generator. This sub-band generator is capable of producing multiple frequency bands, enabling sub-band generation from 3 to 10 GHz with nanosecond switching times. The circuit analysis of the complete transceiver is used to set parameters of components. The analysis indicate that a LNA gain of 20 dB, baseband amplifier gain of 45 dB, matched filter accuracy of five bits, ADC accuracy of two bits, a 60 dB dynamic range of the multi-frequency generator, and front end offset voltage of less than 30 mV is required to achieve a 10 dB SNR. Hspice simulation utilizing 0.35/spl mu/m CMOS technology suggest that the power consumption of the sub-band generator is 8 mW from a 1.8 V power supply.
