Description of the Main Building Blocks
Oscillator
The AMIS-70020 integrates an oscillator that functions
without any external components. The maximum accuracy
of the time measurement can only be obtained if the
measured time is calibrated with the actual oscillator
frequency. This can be done since the oscillator output
frequency can be measured by the microcontroller on the
Q_out pin after the measured counter value has been
shifted out the register.
Comparator
When VCC < VDD – VTH, the comparator output
(CUT_OFF) is commuted. CUT_OFF signal is used by the
digital control to put the circuit in cut_off mode.
