ABSTRACT:
The current peak detector can be described as four separate sections. The first section is power distribution. The second is the analog section where the Idd current transient peak is first detected. There are two analog sections, one for Idd internal, and another for Idd external. The third section is the automatic multiplexer that controls which of the two analog sections will drive the digital section. The fourth and final section is the digital section where a voltage that is analogous to the peak current is converted to a DC voltage level with infinite memory. The digital section performs the logic function of replacing any prior digitized voltage peak with any higher voltage peak that may occur during the test period.
