CMOS voltage reference with multiple outputs
IET Circuits, Devices & Systems, 2008 A voltage reference with two outputs is presented. Both of them are insensitive to temperature, supply voltage and threshold voltage. One of the outputs is ∼0.8 V, and the other one is ∼0.38 V. For the output voltage of 0.8 V, this voltage variation because of supply voltage change from 2.0 to 3.5 V is ±0.66%, and because of temperature change from 0 ...
