As operating speeds increase, the effect of the internal impedance at the input nodes become more critical to achieving the desired frequency response. The most common issues revolve around the common ...

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 ...

To ensure the stability of dc-dc converters, most power-system designers adhere to the common rule that input source impedance should be small compared to the converter's input impedance. Not all ...

This file type includes high-resolution graphics and schematics when applicable. Instrument amplifiers (INAs) are widely used for signal conditioning in data-acquisition systems and telemetry. Their ...
