Estimation of output current from digital IC by using nonlinear impedance
S. Kazama, Shinichi Shinohara, R. Sato · 2002
The estimation of electromagnetic radiation from a digital IC is studied. In this estimation, digital IC output current which is calculated by using a linear equivalent circuit, was used. The calculated values of output current from a digital IC were in relatively good agreement with the measured values. In some cases, however, the calculated values were different from the measured values. This occurs when the nonlinear characteristics of a digital IC are large. By considering the nonlinear characteristics, the output current from a digital IC can be calculated more accurately.
