چکیده
This paper presents a high speed and low energy transceiver for 10mm long minimum width on-chip global interconnects. To improve the link bandwidth, the transmitter employs a capacitive-resistive pre-emphasis technique and the receiver employs the AC-coupled Resistive Feedback Inverter (RFI) de-emphasis technique. Exploiting two emphasis techniques, the proposed interconnect achieves 1.26GHz bandwidth which is 20 times improved compared to conventional link. As a result, it achieves error-free 3Gb/s data rate and consumes less than 0.6pJ/b during transmission by using low-swing and pulse signaling. The test chip is designed using 1.8V 0.18 m 6M CMOS technology.

A Power Efficient 2Gb/s Transceiver in 90nm CMOS for 10mm On-Chip Interconnect
Global on-chip data communication is becoming a concern as the gap between transistor speed and interconnect bandwidth increases with CMOS process scaling. In this paper a low-swing transceiver for 10mm long 0.54μm wide on-chip interconnect is presented, which achieves a similar data rate as previous designs (a few Gb/s), but at much lower power than recently published work. Both low static pow...

One of the most difficult problems that remains to be solved in wire interconnect architectures is the achievement of lower latency and higher concurrency on a shared bus or link without increasing the power and circuit overhead. Novel improvements in short distance onand off-chip interconnects can be provided by using a multi-band RF interconnect (RF-I) system. Unlike the conventional currento...
متن کاملTransceiver in 90 nm CMOS for 10 mm On - Chip Interconnects
The bandwidth of global on-chip interconnects in modern CMOS processes is limited by their high resistance and capacitance [1]. Repeaters that are used to speed up these interconnects consume a considerable amount of power [2] and area. Recently published techniques [1-4] increase the achievable data rate at the cost of high static power consumption, leading to relatively high energy per bit fo...

Owing to the extent of multimedia data transmission, the demand for large-capacity communication systems has increased drastically. In order to meet this demand, highspeed time-division multiplex (TDM) systems have been developed thus far [1]–[3]. Several component ICs using various high-speed devices such as HBTs based on SiGe [1] and compound semiconductor devices [2] have been studied for po...

This thesis work explores the use of equalization techniques to improve throughput and reduce power consumption of on-chip interconnect. A theoretical model for an equalized on-chip interconnect is first suggested to provide mathematical formulation for the link behavior. Based on the model, a fast-design space exploration methodology is demonstrated to search for the optimal link design parame...
