... "squaring" the already small envelope input, and can be safely ignored. The theoretical analysis leads to an intuitive understanding of the nonlinear behavior, as well as a strategy for high-linearity high-efficiency RF amplifier design, as will be explained below. Since the envelope-dependent mixin ...

... Although designed for operation from a +5V logic supply, the MAX742 works well from 4.2V (the upper limit of the undervoltage lockout threshold) to +10V (absolute maximum rating plus a safety margin). The upper limit can be further increased by limiting the voltage at V+ with a zener shunt or series ...

... communication with a CC1000 RF transceiver running on 3.0 V. If we handle the MCU->CC1000 signals first, the problem here is that a 5 V signal from the MCU will violate the absolute maximum rating for pin voltage on the CC1000, which is VDD+0.3V. This means that you risk destroying the CC1000 by app ...

Ground loop (electricity)

In an electrical system, a ground loop is an equipment and wiring configuration which results in excessive unwanted current in a conductor connecting two points that are supposed to be at the same electric potential, often ground, but are actually at different potentials.Ground loops are a major cause of noise, hum, and interference in audio, video, and computer systems. They do not in themselves create an electric shock hazard, the inappropriate connections merely create a not necessarily very good instance of Electrical_bonding, which is explicitly required by safety regulations in certain circumstances. In any case the voltage difference between the ground terminals of each item of equipment is small. A severe risk of electric shock occurs when equipment grounds are improperly removed in an attempt to cure the problems thought to be caused by ground loops.
