Improved Unsaturated to Saturated Logic Level Translation With Automatic Change on Reference Voltage

Ganesh Adhikari, Dr. Shashidhar Ram Joshi

Abstract


This research relates to ECL to TTL converters for converting True ECL level signal to True TTL level signals and more particularly to converters which can operate at very fast switching speeds. It is an important achievement of this research work that resolves mixed voltage incompatibility between different parts of a system that operates in multiple voltage domains. They are common in today’s complex systems, especially when interfacing with legacy devices with performance-optimized application specific level shifters for standard interfaces (e.g. SD card, SIM card). Another very important feature of the circuit is that the ECL reference voltage will automatically adjust by an appropriate percentage to compensate any shift slightly due to temperature change by utilizing the concept of voltage divider rule.
