In some applications, a linear amplifier is required which has different gains with regard to the polarity of the input signal. Figure 1 shows an inverting amplifier which is linear within the second ...

Whenever you need an amplifier or have a related linear-circuit design problem, most of you will turn to an op amp as a solution. Op amps are a good choice because of their universal versatility to ...

The design and modelling of power amplifiers are central to advancing high-frequency applications, including wireless communication, radar, and satellite systems. In these devices, accurately ...

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 ...

Understanding the capabilities and differences of linear and pulse-width modulated (PWM) AC power sources is especially helpful when determining which models meet your requirements. And, the selection ...
