[PSES] Analog Designers Notebook - Improving Opamp RF immunity

[Doug Smith]

Hi Everyone, I thought I would post an analog design Technical Tidbit this month: Technical Tidbit - November 2013 Analog Designer's Notebook Part 1 - Improving Opamp RF Immunity Abstract: Radio frequency (RF) energy can cause DC offset and noise in opamp circuits, even voice frequency circuits. The RF energy may originate from external sources or even be high frequency noise from digital circuits on the same PCB. A simple way of improving the RF immunity of an opamp circuit that can help in many cases is described as well as a precaution that should be taken when this technique is used.
