The current differencing buffered amplifier (CDBA) is a derivative of the current feedback operational amplifier (CFOA), originally proposed by Acar C and Ozoguz S. The main advantage of a CDBA is ...

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 ...

Accurately measuring current flow is a standard requirement in several applications (Fig. 1). Depending on the specific need, the options available to designers can include discrete designs assembled ...

Over the years the semiconductor industry has endeavoured to provide circuit designers with a cheap, high quality, versatile analogue building-block and many amplifier designs have been manufactured ...

I ask these types of questions frequently. Do we need another “widget” when everybody and their grandmother makes one of these nowadays? Well, I have not seen any other amplifier that can beat the ...
