Combinational Logic Design

Pass Gate Logic An alternative to implementing complex logic is to realize it using a logic network of pass transistors (switches). We have already observed a series connection of two switches implements AND while a parallel connection implements OR. B is not redundant, it ensures a low impedance path exists when B is low. Switch Network Regeneration is performed via a buffer.
