Abstract
In this communication, RC tree networks are analyzed in terms of the energy dissipated during an input transition. A closed-form analytical model of the energy consumption is derived for arbitrary values of the input rise time by introducing a suitable first-order equivalent RC circuit, which avoids the explicit pole-zero evaluation. The proposed expression of the energy consumption has an evident meaning, thereby affording a deeper understanding of the network dissipation. Moreover, the energy model is sufficiently simple to be used in pencil-and-paper calculations. Extensive SPICE simulations confirm that the model has an adequate accuracy, as its error is typically within 5%.
