Temperature influence on power consumption and time delay

Abstract

Both the energy consumption and the propagation time delay are very critical parameters of contemporary integrated circuits. It is obvious that a circuit should consume energy as small as possible and ought to work with maximum speed and efficiency. However, these parameters are dependent on temperature, which can change with both external (e.g. high surrounding temperature) and internal (e.g. power dissipated in the circuit) conditions. The article presents the temperature influence on energy consumption and propagation time delay of CMOS ASIC circuits at the example of AMI Semiconductor 0.7 /spl mu/ CMOS C07MD technology (former Alcatel MIETEC CMOS 0.7 /spl mu/m-C07MA-C07MD). The gate was tested under the two conditions: controlled by ideal trapezoid pulse signal, and controlled by real output signal that came from previous gate.
