When selecting an operational amplifier (op amp), you have many parameters to consider. DC parameters such as input offset voltage and input bias current are easier to account for because they do not ...

Editor’s note: My good friend and long-time colleague, Michael Steffes, expands upon my introduction article, Rauch filter basics, and adds some very useful and practical insights into the Rauch ...

Current-feedback (CFB) op amps have earned their reputation in many applications that need bandwidth, without compromising other noise and high-speed characteristics. They have served these needs ...

Until now, very high-speed Operational Amplifiers (OP AMPS) have offered a top bandwidth of about a gigahertz. The addition of silicon germanium (SiGe) to a high-speed bipolar-CMOS process results in ...

Linear Tech is aiming at high-impedance sensor transimpedance amplifiers with an op-amp that requires only 3fA of bias current (typical at 25°C) while offering 500MHz gain bandwidth product. Potential ...

National Semiconductor has added three op amps with voltage feedback and rail-to-rail output options. The LMH6622 has an input voltage noise of 1.6nV per root hertz and input current noise of 1.5pA ...

Linear has announced two FET-input single and dual op amps for high speed transimpedance amplifier (TIA) and buffer applications. With just 3fA bias current at 25°C and 4pA max over the entire -40 to ...

Achieving an optimal balance between high performance and power consumption in mobile-device designs is a tricky task, especially when it comes to operational amplifiers. What is driving the power vs.
