ABSTRACT:
An active pull-up circuit is provided which is process compensating. The active pull-up circuit contains a voltage reference which drives a source follower. The inverting output of the source follower controls a pull-up device which is in parallel with an active pull-up device. The active pull-up device can be much smaller in size since it is now assisted by the controlled pull-up device. The controlled pull-up device is held off until the active pull-up device pulls up the bus or line connected to the active pull-up circuit to a predetermined voltage level.
