Abstract :
Self-heating effects in bipolar comparators manifest themselves as signal-dependent output transition timing variation. A circuit-based approach for the compensation of these effects is presented here. A comparator circuit utilizing the proposed compensation scheme has been designed, and simulation results comparing the timing accuracy of this comparator to that of an uncompensated comparator and of a comparator employing simplified compensation scheme are presented.
