There are various reasons why you might need to split a voltage rail in your design. Perhaps the design contains a sensor or an IC that requires a bipolar supply, or you need to make the best use of ...

The very basics of operational amplifiers. Learn comparator, inverting, and non-inverting op-amp configurations. An operational amplifier, or op amp, is a dc-coupled high-gain electronic voltage ...

Although I used op amps in many feedback loops over the years, the subject of transconductance op amps versus voltage feedback op amps has always intrigued me. Therefore, I thought it would be a good ...

Author Mazi Hosseini describes a simple, low-cost, voltage-controlled current source using two op amps that provides a good range of current and maximum load. One challenge in circuit design is ...

It is a classic problem when designing with op amps: you need the output to go to zero, but — for most op amps — you can’t quite get down to the supply rail. If your power options are a positive ...

Power operational amplifiers (POPs) are becoming increasingly common in control circuitry. Their primary advantages over conventional amplifiers are reduced part counts, increased reliability, and ...
