Abstract
A circuit device includes an A/D conversion circuit that A/D converts a signal output from a sensor element, an interface circuit that receives filter setting data that determines a characteristic of each of a plurality of digital filtering processes, a storage circuit that stores the filter setting data, and a signal processing circuit that sequentially performs each of the plurality of digital filtering processes with characteristics determined by the filter setting data on a digital signal output from the A/D conversion circuit.
Claims9
A circuit device comprising:
- an A/D conversion circuit that A/D converts a signal output from a sensor element;
- an interface circuit that receives filter setting data that determines a characteristic of each of a plurality of digital filtering processes;
- a storage circuit that stores the filter setting data;
- and
- a signal processing circuit that sequentially performs each of the plurality of digital filtering processes with characteristics determined by the filter setting data on a digital signal output from the A/D conversion circuit.
A method of setting a circuit device including an A/D conversion circuit that A/D converts a signal output from a sensor element, an interface circuit, a storage circuit, and a signal processing circuit that performs a digital filtering process on a digital signal output from the A/D conversion circuit, the method comprising:
- inputting filter setting data that determines a characteristic of each of a plurality of digital filtering processes into the interface circuit, and storing the filter setting data in the storage circuit;
- and
- causing the signal processing circuit to sequentially perform each of the plurality of digital filtering processes with characteristics determined by the filter setting data on the digital signal output from the A/D conversion circuit.
