11. The op-amp's output voltage is limited by the supply voltage . 12. Microprocessor games have electronic power supplies that automatically compensate for inaccurate AC supply voltages . 13. To offset this effect and maintain normal operation, the supply voltage is gradually lowered. 14. The little-used negative supply voltages , however, have a ?0 % tolerance. 15. For example, they may have a wider range of supply voltage or temperature tolerances. 16. These capacitors decouple every IC from every other IC in terms of supply voltage dips. 17. Similarly, their resistance is only valid when the correct DC supply voltage is present. 18. Special attention was given to the closeness of the governing to ensure a stable supply voltage . 19. Generally, supply voltages must be within ? % of their nominal values at all times. 20. CMOS chips often work with a broader range of power supply voltages than other logic families.
