North Reading, MA–January 2007–Rotel Electronics, well-known throughout the world as manufacturer of affordable high-end audio and video components, has introduced a new high-performance stereo ...

Maybe you are familiar with the op-amp as an extremely versatile component, and you know how to quickly construct a huge variety of circuits with one. Maybe you even have a favorite op-amp or two for ...

Modern operational amplifiers (op amps) and instrumentation amplifiers (in amps) provide great benefits to the designer, when compared with discrete semiconductors. But all too often, some very basic ...

Presented here is a PWM amplifier circuit (Figure 1) built around a two quadrant driver circuit that can amplify 3.3V or 5V signals to a higher level. Figure 1 PWM amplifier circuit built around a two ...

Modern op amps have much higher operating bandwidths than their predecessors. These new devices are excellent building blocks that can greatly simplify the design and construction of high-bandwidth ...

Two of the most often used amplifier building blocks in audio amplifier design are the common emitter amplifier with emitter degeneration and the emitter follower using the same circuit biasing. The ...
