Claim:
1. A driver circuit for outputting a result of classifying and counting photons according to energy level to a column line, the circuit comprising: a multiplexer configured to receive a result from a counter, the multiplexer configured to output a first signal based on the result from the counter; a first inverter configured to receive the first signal from the multiplexer and a second signal from a power supply, the first inverter configured to output a third signal to the column line based on receiving the first signal; and a first switch coupled between the power supply and an input terminal of the first inverter, the first switch being external to the multiplexer, the first switch and the multiplexer being directly coupled to the input terminal of the first inverter, the first switch being configured to selectively supply the second signal from the power supply to the first inverter.
