This article describes the voltage inverter circuit. The circuit is very simple, very cheap, very effective. This simple circuit is a better solution to provide a dual op amp from a single battery problems. Simply take an active circuit voltage and be transformed. It only uses a 555 timer and a few other passive components, so it will not add much to the size and cost of the project. V can be anywhere from 4 to 16 V. - V is a volt less than V . So for -12 v output, use the 13 v input. Maximum output current of the circuit is about 280 ma, enough a few amplifiers. In order to better regulation, 79 years Luo series regulator can be used. A Zener diode can also be used regualte output voltage. If you want a more thorough grasp of the principles, you can find out about important components of the circuit, such as: 1N4148 . 

This is the schematic of the Voltage Inverter
