The nominal value of the capacitors, at steady state, is few pF and when an acceleration is applied the maximum
variation of the capacitive load is few hundredths of pF.
3.2 IC Interface
The complete signal processing uses a fully differential structure, while the final stage converts the differential
signal into a single-ended one to be compatible with the external world.
The first stage is a low-noise capacitive amplifier that implements a Correlated Double Sampling (CDS) at its
output to cancel the offset and the 1/f noise. The produced signal is then sent to three different S&Hs, one for
each channel, and made available to the outside.
The low noise input amplifier operates at 200 kHz while the three S&Hs operate at a sampling frequency of 66
kHz. This allows a large oversampling ratio, which leads to in-band noise reduction and to an accurate output
waveform.
All the analog parameters (output offset voltage and sensitivity) are ratiometric to the voltage supply. Increasing
or decreasing the voltage supply, the sensitivity and the offset will increase or decrease linearly. The feature
provides the cancellation of the error related to the voltage supply along an analog to digital conversion chain.
3.3 Factory calibration
The IC interface is factory calibrated to provide to the final user a device ready to operate.
The trimming values are stored inside the device by a non volatile structure. Any time the device is turned on,
the trimming parameters are downloaded into the registers to be employed during the normal operation thus
allowing the final user to employ the device without any need for further calibration.
