This paper presents a baseband noise reduction method in the receiver for UHF RFID readers. The signal captured from the transmitter after passing through the main delay components is fed as an LO signal into the down-converter in the receiver. At the down-converter, the LO signal and the leakage signal from the transmitter to the receiver are mixed with each other. The matching of the delay between...
This paper presents novel nonoverlapping cuspid-pulsed flip-flop, which consists of a cuspid-pulse generator and a domino-like latch. The cuspid-pulse generator supplies the domino-like latch with nonoverlapping negative and positive cuspid-shape pulses. The flip-flop allows the elimination of the second stage in the conventional semi-dynamic pulse-based flip-flops, leading to a significant reduction...
Chirped waveguide Bragg gratings are fabricated by tapering the width of the core involving uniform grating. A residual dispersion (+170 ps/nm) in a 40-Gb/s transmission system is compensated by adjusting temperature gradients in the waveguide.
