Multi-step incremental switching scheme

A capacitance measurement circuit cancels background capacitance while reducing charge leakage and supply ripples during reset phases and integrate phases. The capacitance measurement circuit operates a first switch into a linear mode causing a first resistance in the first switch, and after a delay...

More Information
Summary:A capacitance measurement circuit cancels background capacitance while reducing charge leakage and supply ripples during reset phases and integrate phases. The capacitance measurement circuit operates a first switch into a linear mode causing a first resistance in the first switch, and after a delay, operates a second switch into a saturation mode causing a second resistance in parallel to the first resistance.
