This paper introduces a fully-integrated wireline transceiver operating at 40 Gb/s. The transmitter incorporates a 5-tap finite-inpulse response (FIR) filter with LC-based delay lines precisely adjusted by a closed-loop delay controller. The receiver employs a similar 3-tap FIR filter as an equalizer front-end with digital adaptation, and a sub-rate clock(More)
This paper presents a complete design of 100GbE chipsets including gearbox TX/RX, LDD and TIA/LA arrays. Figure 7.3.1 shows the architecture, where 10×10Gb/s input data is serialized into 4×25Gb/s bit stream by a 10:4 serializer (i.e., gearbox TX). A 4-element LDD array subsequently drives 4 laser diodes, emitting 850nm light into 4 multimode fibers (MMFs).(More)
In this paper, a satellite antenna controller bases on fuzzy theory is proposed. The high accuracy of satellite antenna controller plays an important role in the tracking system, but the dynamic characteristic of satellite antenna controller is nonlinear, and the noise in the external environment may affect the system. The fuzzy controller has high(More)
Next generation optical and electrical communications such as chip-to-chip serial links or 100GbE require very-high-speed transceivers. At tens of Gb/s, both transmitters and receivers suffer from inadequate bandwidth and high power consumption. One major difficulty arises from the performance degradation of FIR-based FFEs as the FF’s CK-Q delay becomes(More)
