Originally, operational amplifiers (op amps) were not thought of as candidates for RF design, but the advent of newer, faster devices has now made them an attractive option for some applications. The ...

This circuit in Figure 1 produces the amplitude curve illustrated in Figure 2. 2. Wideband Response for Circuit of Figure 1. The voltage gain of the op amp stage itself is 20, but this is cut in half ...

With so much attention on IBOC, it is appropriate to step back and review the basic principles of RF amplifiers. The radio transmitter is a collection of stages. Each stage modifies the signal in some ...

RF power amplifiers are going wide and high to meet wider frequency ranges and the need for more bandwidth. Many wireless electronic systems operate over wide frequency ranges and the need for more ...

Op Amps Continue To Flourish SINCE THE INTRODUCTION OF THE FIRST monolithic bipolar operational amplifier (op amp) in the mid-sixties by Fairchild Semiconductor (www.fairchildsemi.com), the technology ...

In the first article about measurement systems we looked at sensors as a way to bring data into a measurement system. I explained that a sensor measures physical quantities which are turned into a ...

Engineers are frequently faced with the challenge of developing applications to meet a wide range of requirements. Usually, these requirements are difficult to fulfil simultaneously. One example is ...

The ADHV4710 op amp operates on dual supplies from ±12 to ±55 V, delivering output current of ±100 mA at the higher voltages. A ±1,300-V/μs output slew rate into capacitive loads up to 1 nF (1000 pF).

In the world of audiophilia there are arguments that rage over the relative merits of particular components. Sometimes this can reach silly levels as in the high-end ALPS pot we once saw chosen as a ...
