Title:
A signal-processing circuit and a control circuit
Document Type and Number:
Japanese Patent JP6227890
Kind Code:
B2
Abstract:
Disclosed is a signal processing circuit including an analog-to-digital converter, an arithmetic processing unit electrically connected to the analog-to-digital converter, and a first register electrically connected to the arithmetic processing unit. The extremely small off-state current of a transistor included in the first register allows the first register to retain a signal output from the arithmetic processing unit. This structure enables stationary driving of a load even if the signal processing circuit is turned off, which contributes to a reduction in power consumption of an electronic device having the load.
