ECL and CMOS circuits are frequently utilized in semi-conductor circuit technology; the ECL circuits (emitter-coupled logic) have the shortest switching times of all logic families. These switching times lie in the region of a few nanoseconds and also partly extend below one nanosecond. Complementar...
Another object of the invention is to provide a circuit for driving a TTL bus from ECL logic. A further object of the present invention is to provide a fast circuit for driving a TTL bus from an ECL circuit. A still further object of the invention is to provide a circuit for driving ...
CMOS or TTL logic levels have larger voltage swings (CMOS level has a voltage swing of approximately 5.0 volts and TTL level has a voltage swing of approximately 3.0 volts) so that they are easier to meet the required levels. This means that CMOS or TTL logic circuits can be fabricated at...
Summary form only given. The full leverage offered by E-beam lithography has been exploited in a 0.25- mu m bipolar process. The tight overlay capability was shown to provide a significant advantage in shrinking the overall transistor size. In conjunction with a device technology optimized to ...
It should not be used for propagation delays as many gate functions are achieved internally without incurring a full gate delay. Figure 2. 8-BIT Binary Counter Logic Diagram Table 4.
