a monolithic off-chip iddq monitor
An integrated off-chip I/sub DDQ/ measuring unit (IOCIMU) is described in this paper. The semi-digital current monitor is designed for the use with standard automatic test equipment (ATE). Simulations of the monolithic monitor implemented in a 2-/spl mu/m BiCMOS technology show an accuracy better than 1\% for currents in the range from 0 to 1 mA and a test rate up to 10 kHz.
