21. Another cause is the supply voltage exceeding the absolute maximum rating, often from a junction. 22. Many systems also measure the power supply voltages , to guard against slow power supply degradation. 23. Video cards and motherboard northbridges are components which frequently require hardware modifications to change supply voltages . 24. Calculate this power-supply voltage . 25. Domestic supply voltage is 220V AC . Electricity is generated mainly by thermal and hydroelectric power plants. 26. To see why, consider a single-ended digital system with supply voltage V _ S. 27. How the numerical codes map to supply voltages is typically specified in tables provided by component manufacturers. 28. Loss from subthreshold leakage can be reduced by raising the threshold voltage and lowering the supply voltage . 29. This means that supply voltage can theoretically be anywhere between 216V and 253V depending on local conditions. 30. Supply voltage should be slightly above 40V . The voltage gain can be adjustable 2x to 8x.
