Abstract
A bias supply configured for predicting behavior of one or more aspects of a plasma load by measuring a current waveform is disclosed. The bias supply applies an asymmetric periodic voltage waveform and a corresponding current waveform. The asymmetric periodic voltage waveform includes a first section comprising a positive pulse peak and a second section comprising a negative voltage ramp. The bias supply receives data about the current waveform during the first section, and based upon the received data, provides information about a plasma load.
