Tsukure Mad Labs Negative Voltage Generator
In electronics applications sometimes we need negative voltage. However getting a negative supply source is not a reliable option, when it is needed for low current applications. For many electronic circuits which require low power, we cannot go for a negative voltage power source. For the applications of reference or low power purposes one can go for circuits which can generate negative voltage from positive voltage supply.
There are many circuits for this purpose. Here we have designed a simple negative voltage generator circuit. This circuit is developed from 555IC timer circuit.
