FUNCTIONAL DESCRIPTION
The UZZ9000 is a mixed signal IC for angle measurement
systems. The UZZ9000 has been designed for the double
sensor KMZ41. It combines two analog signals (sine and
cosine) into a linear output signal. The analog
measurement signals on the IC input are converted to
digital data by two ADC’s. Each ADC is a Sigma-Delta
modulator employing a 4th order continuous time
architecture with an over-sampling ratio of 128 to achieve
high resolution. The converter output is a digital bit-stream
with an over-sampling frequency of typically 500 kHz.
The bit-stream is fed into a decimation filter which
performs both low pass filtering and down-sampling. The
IC has two input channels each of which has its own ADC
and decimation filter. The two decimation filter outputs are
15-bit digital words at a lower frequency of typically
3.9 kHz which is the typical sampling frequency of the
sensor system. The digital representations of the two
signals are then used to calculate the current angle by the
ALU. This calculation is carried out using the so-called
CORDIC algorithm. The angle is represented by a 13-bit
resolution. A DAC converts the digital signal back to the
analog domain.
