摘要： Disclosed is a digital-analog converter including a current generation section, a current source transistor bias voltage keeping section, a cascade transistor group switch section, and a conversion section. The current generation section has at least one current source transistor group including a plurality of current source transistors and generates an output current based on a value of a digital input signal. The current source transistor bias voltage keeping section has a plurality of cascade transistor groups each including cascade transistors connected in series to the current source transistors and keeps bias voltages of the current source transistors constant. The cascade transistor group switch section selects one of the plurality of cascade transistor groups. The conversion section performs current-voltage conversion of the output current supplied via the selected cascade transistor group.

摘要： The present technology relates to a signal processing device and a method, an imaging device, and an imaging apparatus that are designed to reduce occurrences of A/D conversion errors. A signal processing device of the present technology includes: a comparing unit that compares an analog signal output from a unit pixel with a predetermined voltage; a switching unit that switches reference voltages to be supplied to the comparing unit as necessary, connects one of the reference voltages to the comparing unit, and connects another one of the reference voltages to a predetermined load capacitance, the reference voltages being of different gradation accuracies from each other; and a measuring unit that measures timing of a change in a result of the comparison performed by the comparing unit. The present technique can be applied to imaging devices and imaging apparatuses, for example.
