Interfacing Sensors with Anadigm FPAA

There are lots of info regarding sensing, open loop, sensor linearization, sensor, gain, selection, signal, range, noise, position sensing, synchronous demodulation, filtering, and error are explained inside this technical note. Inside this technical note you can find info related to temperature sensing, offset, resistance, voltage, loop gain, clock phase, conditioning, sensor signal conditioning, signal conditioning, sensor signal, settling time, and phase.

This technical note presents explanation about operating limits, filter, filter response, effect, sensor, sampling, differential signals, input signal, signals, leakage, cell filter, and output. Here are grabbed from this technical note:

Using the Chopper Input “Chopping” modulates the input signal with a square wave Low freq noise and DC offsets are pushed out to the clock freq (for easy filtering) Slewing and settling limitations mean the chopper output is not “ideal” To recover the “ideal” output, sample in phase2 at twice the chopper frequency To boost the gain, use offsetcompensated CAMs, sampling in phase2 at twice the chopper frequency

Additionally, the technical note presents information such as temperature, sensitivity, thermal effects, single ended signals, clock frequency, signal conditioning needs, cell, frequencies, output waveforms, detection, frequency, and leakage errors.
