For the past 30 years, the standard VDD for digital circuits has been 5V. This voltage level was used because bipolar transistor technology required 5V to allow headroom for proper operation. However, in the late 1980s, Complimentary Metal Oxide Semiconductor (CMOS) became the standard for digital IC design. This process did not necessarily require the same voltage level
