手机及数字消费类电子产品中的模拟电路设计技术将迎来巨大变革。引发此次变革的是混合信号单芯片中数字电路工艺的发展。从90nm到65nm、再到45nm,随着工艺技术的发展,数字电路所使用的电源电压也开始向1V～0.8V的低电压化方向发展。受数字电路工艺的影响,模拟电路迟早也会引入180nm、130nm甚至90nm的工艺。届时,模拟电路部分的驱动电压也要降至1V以下。但是,目前还不太现实。

Analog circuit design technology in mobile phones and digital consumer electronics products will usher in tremendous change. Triggered by this change is the development of digital circuit technology in mixed-signal single-chip. From 90nm to 65nm, and then to 45nm, with the development of process technology, digital power supply voltage used by the circuit also began to 1V ~ 0.8V direction of the development of low voltage. Affected by the digital circuit technology, sooner or later the analog circuit will introduce 180nm, 130nm or even 90nm process. By then, the analog circuit part of the drive voltage also dropped below 1V. However, it is not realistic yet.
