[摘要]：A current mode periodic output parallel two-rail code (TRC) checker, suitable for the implementation of high fan-in embedded checkers, is presented. The new checker is characterized by high testability, high-speed operation, and low silicon area requirements. The circuit has been designed, for various fan-in values, in a 0.18 mu m technology, and electrical simulations have been carried out to validate its operation, considering process, power supply, and temperature variations as well as variations of the electrical parameters. |
