CMOS supply voltage scaling for temperature independent gate delay is investigated. It is found that the optimum supply voltage which results in temperature insensitive operation is proportional to the threshold voltage. This voltage enables a single battery cell operation. CMOS technologies with 0.35- and 0.25-μm size features are used as examples in this study
