The input signal for the ADC signal chain could be a sensor, a signal from some source, or the feedback of a control loop. It’s well-known that in traditional discrete-time sigma-delta ...

As shown in Figure 7 and Figure 8, the LTspice input impedance results were created by taking the derivative of input voltage with respect to input current as the input is swept across a large ...

If a common-mode input signal is present with a frequency of 100kHz (1E+05Hz), you can see from the curve that the op amp has approximately 100dB of CMRR at that frequency. Equation 1 converts 100dB ...

With its wide range of input common-mode support and programmable gain options, any sensors or input signals with a wide range of signal magnitude can be interfaced with the ADC. An example of input ...

4. The varactor front end will change a dc voltage to a modulated ac waveform. In this Spice simulation, a 500-Hz input signal is modulated by the 347-kHz oscillation created by a tank circuit on ...
