Modeling of I2L Injection Logic Structures

This paper describes the static and dynamic modeling of injection logic structures (based on the special physical properties of these devices) with a view to optimization and improved simulation in the analysis of these circuits. In order to define the performance limitations and to guide the optimizing procedures of a new family of bipolar logic, the I²L, its operation must be analysed in detail and its electrical model should be established. Due to the technological particularities and the operating conditions of these structures we first of all establish the steady state model of an I²L gate. A dynamic model is then proposed that takes account of the charges stored in the different zones of the structure.
