Bipolar and unipolar voltages and their significance

[honyeehong8692]

Hello all!

I'd like to clarify on the the differences of bipolar and unipolar voltages. I do understand that they both are used to trigger a number of semiconductor devices.

Please and thank you!

Probably unipolar voltages are a single voltage referenced to zero volt as ground. Most logic gate power supplies and signals are unipolar.

Bipolar has a positive and a negative voltage referenced to zero volts. There was a time when analogue electronics using op-amps which needed both a (+)ve and (–)ve supplies. The signals were relative to zero volts. Now, rail-to-rail op-amps will run on low voltage unipolar supplies.

Thank you very much, @Baluncore!
