How it works
Currently, the project only contains a single NPN comparator. The comparison of ua[0] and ua[1] is sent to ua[2]. The power gate is driven by ui_in[0], drive this high to enable the comparator.
How to test
Set ui_in[0] low to disable the comparator, as there is no power gating. After selecting the project, set ui_in[0] high and apply analog signals between 0.0 V and 1.2V to ua[0] and ua[1]. A mostly-digital signal will be sent to ua[2].
External hardware
None.
