In this paper, we investigate how a particular FPGA architecture can be enhanced by including a single memory array in each logic cluster.

It is also shown that 40% of the logic and memory element inputs should be available outside the cluster.","PeriodicalId":20702,"journal":{"name":"Proceedings of the IEEE 2000 Custom Integrated Circuits Conference (Cat.

With a 2 V supply the measured RMS jitter for the 1 GHz synthesizer output was 3.2 ps. With a 3.3 V supply RMS jitter of 3.1 ps was measured for a 1.6 GHz output. The tunable oscillator has a 1.8% frequency variation over an ambient temperature range from 0 to 85/spl deg/C.
