In a balanced op-amp circuit, the op-amp inputs see equal impedances looking into the circuit. Balanced circuits provide better performance by cancelling some input errors and have a simple R F /R I ...

Power amplifiers (PAs) are pivotal elements in modern wireless communication and radar systems, where enhancing output power and efficiency remains a critical challenge. Recent advances in PA design ...

A few months ago, I wrote a Signal Chain Basics article titled “3 considerations when selecting an op amp.” While that article is very useful for selecting operational amplifiers (op amps) for new ...

Variable Gain Amplifiers (VGAs) implemented in Complementary Metal-Oxide Semiconductor (CMOS) technology have emerged as a critical component in modern analog and mixed-signal systems. These ...

The distortion performance of an amplifier is determined not only by open loop linearity, but also the negative feedback factor applied when the loop is closed. In most practical circumstances ...
