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 ...

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 ...

Demand for voltage-controlled current sources (VCCSs) and multipliers in a wide spectrum of electronics and communication devices always seems to exist. The multipliers employed in circuits like the ...

The Norton amplifier topology brings back the essence of analog design by using clever circuit techniques to deliver strong performance with minimal components. It is not about a brand name—it’s about ...
