An enhanced power meter for SPICE2 circuit simulation

An enhancement to a technique presented by S.M. Kang (IEE J. Solid-State Circuits, vol.SC-21, p.889-91, Oct. 1986) for measuring average power dissipation during a SPICE circuit simulation is described. A modified power meter circuit is discussed that allows power measurement during an arbitrary interval of time, holds a constant final value at the end of the sampling interval, and improves the resolution of the technique. Simulation results comparing the modified power meter with the original power meter are presented to verify the modification. An optional modification to provide for a variable power supply voltage is also included.<
