“…(2) Low frequency wide band phase-shift network Wide band phase-shift network makes two networks connect a signal source in parallel. The signal source splits into two signals to the outputs of the two networks [5,6] . In every frequency point within certain bandwidth, phase-shift difference of the two output signals keeps a constant degree.…”

On the basis of the carrier has a low frequency in underwater electric current communication, carrier phase shift network, low frequency wide band phase shift network and multiplier circuit were designed to realize the single side-band (SSB) modulation. The circuits were designed and debugged. Through testing the actual circuits, sideband suppression ratio obtains 36dB which can satisfy the underwater electric current communication system. It will be stated reference on actual application for SSB modulation with low carrier frequency using phase shift method.

“…These kind of distortions are called inter-symbol interference (ISI) because a symbol is shaped by its adjacent symbols. ISI has been one of the most speed-limiting factors in high-speed transceivers [1][2][3][4][5][6][7][8][9].…”

Decision feedback equalizers (DFEs) play a critical role in high-speed communications through band-limited channels. We implemented a 3-tap DFE receiver for 5-Gb/s data bandwidth. To realize a multi-tap DFE operation, a digitalcontrol scheme is proposed that does not use analog circuits for biasing, such as DACs. In addition to the conventional loop unrolling, several techniques including combined feedback are used to reduce the latency of the feedback path. Fabricated in a 0.13-μm CMOS process, the prototype of the proposed DFE core has an area of 0.009 mm 2 and consumes 8.4 mW from a 1.2-V supply, achieving a BER of less than 10-11 over a pair of 28-inch Nelco 4000-6 board traces.
