Current or voltage measurement circuit, sense circuit, semiconductor non-volatile memory, and differential amplifier

摘要

In a wire pair 120 including a first signal line 120a and a second signal line 120b, the first signal line 120a and the second signal line 120b are laid out so that they have substantially the same stray capacitance. Two output terminals of a measured device 1000 and an input terminal of a differential amplifier 110 are connected together by the wire pair 120. Thus, noise included in the first signal line 120a and noise included in the second signal line 120b become common-mode noise, which are canceled out by the differential amplification of the differential amplifier 110.
