You have designed an op-amp circuit to measure a small voltage. The circuit gain is -10V/V, but it appears that the input impedance to the circuit is effecting the device as it is being measured. How ...
Two very desirable features for a precision measurement system based on an analog-to-digital converter (ADC) are high input impedance and a wide input range, ideally including or extending slightly ...
When considering any new part in the signal chain, input/output impedance is usually an important spec to “bolt” the necessary signal-chain blocks together properly. For a high-speed converter, this ...
Oscilloscope probes are handy tools for making measurements, but they have limitations. For example, they have rather limited bandwidth and that ground clip can create a loop that can pick up noise.
In the “Say It with Me” series, we’ll take a commonly used concept out of electronics and explain it the best we can. If there’s something that’s been bugging you, or a certain term or concept that ...
