Optimizing Dominant Time Constant in RC Circuits
Circuit optimization circuit topology clocks crosstalk delay effects dominant time constant integrated circuit interconnections nonlinear programming RC circuits semidefinite programming
2015/8/12
Conventional methods for optimal sizing of wires and transistors use linear resistor-capacitor (RC) circuit models and the Elmore delay as a measure of signal delay. If the RC circuit has a tree topol...
Optimal Throughput-Delay Scaling in Wireless Networks–Part II:Constant-Size Packets
Throughput-Delay Scaling Wireless Networks Constant-Size Packets
2015/8/12
In Part I we characterized the optimal throughput-delay trade-off in static wireless networks as D(n) = Θ(nT(n)), where D(n) and T(n) are the average packet delay and throughput in a network of n node...

Resistance capacitance circuit measuring signal circuit convex optimization conductance
2015/8/11
We propose to use the dominant time constant of a resistor-capacitor (RC) circuit as a measure of the signal propagation delay through the circuit. We show that the dominant time constant is a quasico...
