XU Ming-li · Experiment Science and Technology · 2010
The design of programmable voltage reference circuit must be with low temperature coefficient,high power supply rejection ratio,range adjustable performance.One designed externally imputed digital signal and converted the reference signal chip resistor divider switch circuit,which did not only provide conversion correspond to the table with a reference voltage,but also provides other required reference voltage circuit.This circuit can be widely used in micro-circuits can be programmed through the Multisim2001 simulation and experiment,get a better voltage output characteristics.
