摘要： According to one embodiment, a semiconductor circuit includes a first transimpedance amplifier and a second transimpedance amplifier. The first transimpedance amplifier is configured to convert an input current to a first output voltage and output the first output voltage from a first output terminal when a reference voltage is supplied to a first input terminal and the input current is supplied to a second input terminal. The second transimpedance amplifier has a circuit configuration similar to a circuit configuration of the first transimpedance amplifier. The second transimpedance amplifier is configured to output a second output voltage from a second output terminal when the reference voltage is supplied to a third input terminal.

摘要： A pulse wave measurement device includes a storage unit and a subtracter. When a light emitting element alternately switches between a lighting state in which the light emitting element emits light into a body and a non-lighting state in which the light emitting element does not emit light, the storage unit stores a value of a first digital signal representing an output state of a light receiving element that receives light transmitted through or reflected by the body at timing of the lighting state, and a value of a second digital signal representing an output state of the light receiving element at timing of the non-lighting state. The subtracter subtracts the second digital signal value stored in the storage unit from the first digital signal value stored in the storage unit.
