Auto-Compensating Temperature Valve Controller for Electro-Rheological Fluid Micro-Channel Cooled Integrated Circuit

摘要

A structure and method of using the structure. The structure including an integrated circuit chip having a set of micro-channels; an electro-rheological coolant fluid filling the micro-channels; first and second parallel channel electrodes on opposite sides of at least one micro-channel, the first channel electrode connected to an output of an auto-compensating temperature control circuit, the second channel electrode connected to ground; the auto-compensating temperature control circuit comprising a temperature stable current source connected between a positive voltage rail and the output and having a temperature sensitive circuit connected between ground and the output, a leakage current of the temperature stable current source being essentially insensitive to temperature and a leakage current of the temperature sensitive circuit increasing with temperature.
