A voltage source has positive or negative polarity depending on its orientation in a circuit. In the case when a voltage source has negative voltage, it just means the negative terminal of the battery is connected to the positive side of the circuit and the positive terminal of the battery is...
In a negative voltage generating circuit, a reference voltage generating circuit generates a first reference voltage. A voltage dividing circuit divides a voltage between the first reference voltage and a negative voltage to produce a division voltage. A comparing circuit compares a second reference ...
It’s not so much that you “need” negative voltage. But sometimes you get negative voltage in a circuit, and it’s good to know what it is. One example where you get negative voltage is in theastable multivibrator circuit. Sometimes you see circuits that need a power supply with three...
A negative-voltage circuit for realizing a flash memory is installed independently and is applied selectively to word lines in response to signals sent from row decoders. Row decoders for specifying word lines need not be installed in the negative voltage circuit. The negative circuit can therefore...
