Abstract
Presented is a low-voltage automatic lock-up biasing circuit with input terminals that accept input voltages, and with an internal node coupled to both input terminals an which takes take the highest of the voltage values applied to the input terminals. This circuit uses a comparator having respective inputs connected to the input terminals and with an output connected to a level shifter. Outputs of the level shifter are coupled to respective enable elements connected between each input terminal and the internal node. The enable elements are driven each by a respective output of the level shifter.
