Making the Most of a Low-Power, High-Speed
... By comparing the OPA890 with the OPA683, we can see the clear advantage of using a current-feedback amplifier for high-gain applications. If we tried to use the OPA890 in a 100V/V application, we would achieve a 1.3MHz, –3dB bandwidth. This performance pales in comparison with the 35MHz bandwidth of ...

A 1.9-GHz Wide-Band IF Double Conversion CMOS
... transmitted LO signal may reflect off of nearby objects and be “re-received,” consequently self-mixing with the local oscillator resulting in a time-varying or “wandering” dc offset at the output of the mixer [11]. This time-varying dc offset together with inherent circuit offsets significantly redu ...

Keysight Measuring High Impedance Sources Using the U8903B
... resistance of 100 kΩ. This is relatively high by most standards but compared to an Oscilloscope or DMM is it actually quite low. Users therefore need to be aware of potential divider effects when measuring sources with output impedance of more than some 10’s of ohms. As well as the 100 kΩ input resi ...

Line filter design of parallel interleaved VSCs for high power
... Cf of the LCL filter. From (4), it is evident that the ωr,trap is less than the ωt . Due to the introduction of the complex conjugate zeros, the roll-off of the high frequency components (higher than the ωt ) is -20 dB/decade. This leads to a poor attenuation of the high frequency harmonic component ...

Caution - leakage currents!
... > In an ideal 3-phase power network with sinusoidal voltages, the sum of all these currents is zero. > In practice, however, there is a continuous leakage current to ground due to strong distortion in the grid voltage. This is also present even if the machine is not running, in other words even if v ...
