This paper reports on our investigations into the performance limits of CMOS datapaths. We have used a combination of single phase clocking, reduced voltage swing logic, moderate pipelining, and custom layout to achieve dramatic speed improvements over conventional design techniques. We have also used a novel fast adder structure and register file. To demonstrate the feasibility and effectiveness of these techniques and circuits, we have designed a test chip including a 64-bit integer datapath and a PLA-based finite state machine for testing. The chip layout was generated using MOSIS design rules and fabricated in the HP CMOS34 1.2-um process. It has been tested and is fully functional at 180MHZ.
