Decision Circuit

AbstractThis paper presents a threshold decision circuit with an adjustable detection window designed in a 90-nm IBM CMOS technology. Together with an RF mixer, the decision Section realizes the circuit implementation of the back-end of a transmitted reference ultra wideband receiver, which is yet to be reported in literature. The proposed circuit is built on a differential amplifier core and avoids the use of integrator and sampling blocks, which reduces the device burden necessary for the architecture. Moreover, the detection window threshold of the design can be regulated by three independent factors defined by the circuit elements. The circuit is tested at an input data rate of 0.1∼2.0 Gbps and the core decision section consumes 9.14 mW from a 1.2-V bias supply (with a maximum capacity/Pdc ratio of 218.8 GHz/W). When compared against other reported decision blocks, the proposed detection circuit shows improved performance in terms of capacity and power requirement.

Uwb Receiver

A Differential Transmitted Reference (DTR) system is analyzed for Ultra Wideband (UWB) communications in a multipath propagation environment with single user transmitted. In order to improve the data rate, The Time-Reversal technology is proposed for the DTR receiver in the paper, which can also resist the influence of Inter/intra Symbol Interference (ISI). Computer simulation is conducted in the presence of an IEEE802.15.3a CM2 channel with Scholtz’s pulse. Analysis and simulation are both shown that the TiR-DTR receiver can improve the data rate of UWB system.
