The realities of physics prevent any of us from attaining the ideal op amp with perfect precision, zero noise, and infinite open-loop gain, slew rate, and gain-bandwidth product. But we expect ...

A common complaint about chopper-stabilized amplifiers is that chopper noise will interfere with the signal and cancel the positive feature of almost-negligible offset voltage and offset-voltage drift ...

Piezoceramic (PZT), or "piezo," actuators are known to be excellent position transducers in the nanometer or micrometer range. These actuators are widely used in many precision applications. PZTs, ...

Noise is all around us, and while acoustic noise is easy to spot using our ears, electronic noise is far harder to quantify even with the right instruments. A spectrum analyzer is the most convenient ...
