What is operational amplifier? An operational amplifier is a DC-coupled high-gain electronic voltage amplifier amplifier that has high gain, differential input, high input resistance, and low output resistance.

EMI Q&A: Reduce on-board DC-DC converter EMI for wireless/IoT devices
https://www.edn.com/emi-qa-reduce-on-board-dc-dc-converter-emi-for-wireless-iot-devices/?utm_content=buffer99ecf&utm_medium=social&utm_source=edn_facebook&utm_campaign=buffer
Self-generated EMI from DC-DC converters has long plagued designers of wireless and IoT devices. The broadband harmonic content often extends up through 1.5 GHz, which includes most wireless protocols, cellular LTE, and GPS/GNSS bands.
Q: Would “ground pours” help isolate noisy signals?
The very best way to isolate “noisy” signals is through proper PCB stack-up; that is all high frequency (>100 kHz) digital signals’ traces should be adjacent to a solid return plane. This will bound the electromagnetic wave. Breaks in the return plane can cause an increase of 15 to 20 dB in EMI (see my video demo on the web site in the References). According to Dr. Eric Bogatin, ground pours more often don’t actually help and can also be detrimental, depending on the board design, because they can appear as “breaks” in the return plane in some cases.

Read this and give electric insulation a second thought
https://www.edn.com/read-this-before-giving-electric-insulation-a-second-thought/
Most design engineers take wire for granted and don’t give much thought to its basic wire-covering insulation. And why should they? In most cases, the insulation fulfills its role of preventing bare conductors from contacting anything else, does it well, and doesn’t cause problems
Today’s fabrication technology makes coating wire with insulation of various types generally a low-cost, high-speed process. That’s in sharp contrast to the early days of electricity when investigators such as Michael Faraday had to manually wrap silk around copper conductors
What you worry about with insulation depends on where you are on the voltage and frequency spectrum. In the low-voltage world of single-digit potentials, insulation is often a relatively minor consideration. Still, insulation has parameters that affect its ability to isolate conductors and relate to RF, fire, mechanical/abrasion, and chemical-resistance performance.
Obviously, the ability of insulation to meet its primary function of doing what its name defines is what most applications need to look at first.
