Michael Gambuzza Electronic Design To transfer maximum power from a circuit to a load, the load’s resistance, R L , must match the source resistance, R O (Fig. 1). In the case of a complex load, Z L , and a resistive source, this transfer can ...

Raymond Ho Electronic Design Most function generators and network analyzers have one port to provide the output signal. If a differential signal is needed, then you may need to acquire a network analyzer with two output ports at great cost. Of ...

By Todd Toporski, Texas Instruments Analog Applications Journal Part 1 Enhancing immunity to RFI and other high-frequency EMI As shown in previous sections, active filtering and CMRR can reliably reduce circuit noise in the device’s ...

By Todd Toporski, Texas Instruments Analog Applications Journal Introduction Automotive, industrial, medical, and many other applications use sensitive analog circuits that must perform their function while remaining immune to noise disturbances in ...

Xiyao Zhang, Texas Instruments Early in my graduate school education, I was working on a project that needed a unity-gain operational-amplifier (op-amp) buffer for a monitoring circuit in our thin film deposition system. As soon as the new module ...

Brandt Braswell EE Times I know there have been many advances in software development for use in design projects. The digital design landscape has permanently been altered by the use of sophisticated software tools for use in design. Design tasks ...

A simple op amp clipping circuit can limit input-voltage excursions into an ADC, thus preventing input overload and possible damage to the converter. It can be a challenge to match the voltage range of an analog signal to the input range of an ...

By Gustavo Castro and Scott Hunt, Analog Devices Analog Dialogue Instrumentation amplifiers (in-amps) can condition the electrical signals generated by sensors, allowing them to be digitized, stored, or used to control processes. The signal is ...

Darwin Tolentino and Sandro Herrera, Analog Devices Analog Dialogue Differential signaling finds useful application in circuits where a large signal-to-noise ratio, high immunity to noise, and lower second harmonic distortion are desired, such as ...

Gustavo Castro, Analog Devices Analog Dialogue Question: Why is the effect of common-mode signals at the output larger than the CMRR specification? Answer: The concept of common-mode rejection ratio (CMRR) is fundamental when working with ...
