Even the simple circuit of Figure 1 seems to be suffering from a low phase margin condition as described in Reference 1 with a sharp resonance at 165MHz. It is important, even in lower speed signal ...

Modern high-frequency amplifiers are a cranky group that lose performance when driving capacitive and reactive loads. Fortunately, you can use some simple tricks to pacify poorly loaded amplifiers.

Let's look at key formulas that are the building blocks for the transfer of electricity: real and reactive power transfer formulas and their basics. The power triangle represents an essential building ...

This article started because a good friend of mine dropped a Panasonic SA-XR50 switch-mode amplifier to me for some basic bench test. This article will NOT be a review of that unit, but an ...

• Electrical power sources supply two types of power to inductive loads: real power in kW and reactive power in VAR. • Power-factor correction circuits can be either an individual style or of the bank ...

A frequency response analyzer ('FRA') is often used to measure gain and phase plots of control loops (Bode plots), filter responses and general frequency domain transfer functions. The FRA generally ...

Two Notes has unveiled the Torpedo Reload II, a feature-packed sequel to its reactive load box and attenuator, and it is a serious piece of kit for any player who has a tube amp and needs some extra ...
