Certain measurement applications, such as for pH (acidity) and bio-potentials, require a high-impedance buffer amplifier. Although several semiconductor manufacturers offer amplifier ICs featuring low ...
An Over-The-Top input stage is shown in Figure 1. At low common modes, the PNPs Q1 and Q2 form a conventional precision differential pair with tail current provided by I1. Figure 1 Over-The-Top Input ...
Wireless receiver sensitivity will benefit from using high gain low noise amplifiers made possible by the high input mixer, writes Richard Wilson Linear Technology has introduced an active ...
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 ...
Modern op amps have much higher operating bandwidths than their predecessors. These new devices are excellent building blocks that can greatly simplify the design and construction of high-bandwidth ...
Circuit simulations are great because you can experiment with circuits and make changes with almost no effort. In Circuit VR, we look at circuits using a simulator to do experiments without having to ...
When considering any new part in the signal chain, input/output impedance is usually an important spec to “bolt” the necessary signal-chain blocks together properly. For a high-speed converter, this ...
