The dynamic CAM cell contains only four n-type transistors. This cell is capable of storing and matching three states, hence the term ternary; these states are: zero (0), one (1) and don't care (X). Circuit simulations show that our dynamic CAM cell performs all the basic operations (read, write and match) at a good speed. In order to use the proposed cell in a CAM array, we developed a cut-off scheme to deal with coupling.","PeriodicalId":221297,"journal":{"name":"Proceedings of the Third International Workshop on Design of Mixed-Mode Integrated Circuits and Applications (Cat.

Such filters may be used in electronic systems where sensors are used to measure physical parameters in order to provide information to the human user. The filter design described in this paper is based on switched-current (SI) design techniques (in particular a biquadratic filter is implemented for this design). With the SI design technique, variations in current values may be achieved with relatively small variations in nodal voltage. In addition, the power supply requirements and fabrication cost will be two considerations for the final choice of implementation method. In this study, current-mode design techniques are used for its suitability in low voltage operation and the ability to create analogue signal conditioning circuitry using a standard digital CMOS fabrication process. This ability to utilize a digital fabrication process may result in a lower cost solution than using an analogue fabrication process.","PeriodicalId":221297,"journal":{"name":"Proceedings of the Third International Workshop on Design of Mixed-Mode Integrated Circuits and Applications (Cat.

The SCB scheme dynamically allocates data regions within the input buffer for each output channel. The proposed scheme provides a high-performance solution to buffered communication switches that are required in interconnection networks. This performance comes from the DAMQ approach as well as the Associative Channel Pointer implementation and novel circuitry. The major components of the SCB are described in detail in this paper. The system has the capability of performing a read, a write, or a simultaneous read/write operation per cycle.","PeriodicalId":221297,"journal":{"name":"Proceedings of the Third International Workshop on Design of Mixed-Mode Integrated Circuits and Applications (Cat.
