Abstract
This communication presents two proposals of CMOS self-timed computation blocks. The main novelty lies on the use of weak (long and narrow) transistors to build the NMOS differential trees performing the logic functions. The most important advantage is that memory elements are not needed to store data when they are operating into a full-handshaking pipelined architecture, thus saving hardware
