A programmable voltage reference for sub-1.2V power supplies

In this project, a programmable bandgap voltage reference is built by current mode approach on CSM018IC process with supply voltage 1.2V. An additional op amp is added to improve the current mirror accuracy and hence reduce the output temperature coefficient. A voltage reference with a single output...
