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 ...

Sponsored by: Texas Instruments. Op amps solve most problems in analog circuit design—if you know how to use them. Here are some resources to help expand your op-amp knowledge base. Whenever you need ...

ALEXANDRIA, Va.—William H. Doherty was an engineer with Bell Telephone Laboratories in 1936 when he invented a circuit that used two tubes running in Class B configuration to act as a linear amplifier ...

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 ...

In Part 1, I discussed the background behind lock-in amplifiers. Here, I’ll cover analog and digital lock-in amplifiers, software-defined radio, de-embedding, and the hardware and software ...

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 ...

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 ...

Learn how power amplifiers work, the common types, and what to lookout for when shopping for amps. You have to find out if the amplifier is a Class A/B analog amp or a Class D digital amplifier before ...
