Various implementations described herein refer to an integrated circuit having multiple stages including a first stage, a second stage, and a third stage. The first stage has first logic structures coupled in series, and the first logic structures are activated with multiple signals. The second stage has second logic structures coupled in parallel, and the second logic structures are activated with the multiple signals. The third stage has a first input, a second input, and an output. The first input is coupled to the first stage, the second input is coupled to the second stage, and the output provides an output signal based on the multiple signals.
