An A/D-chip for accurate power measurement
Reinhard Rauscher, V. Grupe · 1991
The authors describe the development of an integrated circuit. Starting with the specification and the knowledge of usual mathematical procedures the design procedure is discussed. The intention is to support high speed accurate measurement of voltage and current including simultaneous calculations of RMS (root mean square) of voltage and current as well as effective power for arbitrary periodic AC signals. The chip was designed using a 1.5 mu m CMOS process.
