In this paper the effects of multiplier architecture on the overall performance of the OFDM De-modulator for an UWB system are studied. The two commonly used VLSI multiplication algorithms, namely, the Baugh-Wooley algorithm and the Modified-Booth algorithm, are the candidates for this study. Partial product accumulation session can be found in both algorithms. There are two major classes of partial...
This paper investigates and resolves in-channel/quadrature channel (I/Q) imbalances in quadrature band pass delta sigma modulators. These mismatches result in image interference and noise being aliased into the desired signal band, thus degrading the dynamic range of the modulators. A novel dynamic element match shaping scheme is proposed to cancel the aliasing of image interference, noise, and self-image...
A voltage multiplier for passive RFID tags is designed in a 0.35-μm 2-poly 4-metal CMOS technology. Due to the limitations of the technology, an optimized design is difficult to achieve easily. Based on some design studies, an voltage multiplier working at 13.5 MHz is developed and realized on silicon. From the measurement, the output voltage is about 2.5 V and the output current is 6.4 μA. when an...
