Abstract :
In this paper, we divided the switching current of output driver for single ended voltage mode signaling into two parts according to current flowing path. They are the direct current path and the channel current path, respectively. The impedance of the each current path is derived based on the analytical model. The current flowing through two current paths is calculated by using α-power model. From the impedance and current through driver, new expressions to estimate SSN in the CMOS voltage mode driver are derived. The derived expressions have a good agreement with HSPICE simulation results.
