This paper presents a novel current mode four quadrant multiplier. A pair of sub threshold translinear loops and current conveyors are the basic building blocks in realization scheme. The proposed multiplier features simplicity, low power dissipation. The salient features of this approach are; it‟s single ended inputs; since it uses sub threshold region of operation, this make the design intere...

A system simulation environment in Matlab/Simulink of RFID is constructed in this paper. Special attention is emphasized on the analog/RF circuit. Negative effects are concerned in the system model, such as phase noise of the local oscillator, TX-RX coupling, reflection of the environment, AWGN noise, DC offset, I/Q mismatch, etc. Performance of the whole system can be evaluated by changing the...
