    Abstract: The present technology relates to a signal processing device, an imaging element, and an electronic apparatus configured so that a cost increase can be suppressed. A signal processing device of the present technology includes: a comparison unit configured to compare a signal level of an analog signal with a signal level of a reference signal; a selection unit configured to select, from a plurality of reference signals, the reference signal to be supplied to the comparison unit; and a switching unit capable of switching a signal line connected to an input terminal of the comparison unit such that a signal line via which the reference signal selected by the selection unit is transmitted is connected to the input terminal of the comparison unit, wherein the comparison unit includes a floating node as the input terminal, the selection unit includes a signal line in which a parasitic capacitance is caused between the signal line and the floating node as the input terminal of the comparison unit, and the signal line of the selection unit is configured to transmit an identical level of signal in multiple comparison processes performed by the comparison unit. The present technology is applicable to, e.g., an imaging element and an electronic apparatus.
