摘要： Digital LDO is proposed to provide the low noise and tunable power supply voltage to the 0.5-V near-threshold logic circuits. Because the conventional LDO feedback-controlled by the operational amplifier fail to operate at 0.5V, the digital LDO eliminates all analog circuits and is controlled by digital circuits, which enables the 0.5-V operation.

客户服务What''s up with the operating voltages 5 V, 3.3 V, 2.5 V, 1.8 V, etc.?
A lower VDD is required as the gate geometry shrinks. This prevents damage to the CMOS gate oxide and minimizes leakage. When the fabs switched from 0.5um to 0.35um, the thinner gates could only handle potentials up to 3.6V. That led to supplies at 3.3V +/- 10%. With the switch to 0.18um the voltage was reduced further to 1.8V +/- 10%.

客户服务Transform a 0-10V into 0-5V and use op-amps as buffers?
If you don''t have a higher voltage supply (like 12V) available, I would suggest a voltage divider and buffer amplifier. For example: simulate this circuit – Schematic created using CircuitLab. U1 has to be a RRIO (rail to rail on both the input and the output) op-amp (and should be a CMOS type with very low input current to use such high value divider resistors).
