Operational amplifiers (op amps) have proliferated from specialized instruments made from large tubes to tiny monolithic circuits composed of a sliver of silicon, germanium or gallium arsenide. Dozens ...

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 ...

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 ...

Four new broadband op-amp chips achieve industry-leading performance levels for driving high-resolution video signals. The ZL40120/21/22/23 chips post high ratings for bandwidth, linearity, and ...

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 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 ...

What is driving the power vs. performance tradeoffs? How to improve the op-amp bandwidth-to-power ratio. How noise, distortion, and other factors impact the power/performance design decisions. The ...

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 ...
