Abstract
Pixel circuits of a solid-state imaging device are arranged in pixel columns, wherein, for each pixel column, signal outputs of the pixel circuits are connected to a data signal line. The solid-state imaging device further includes comparator circuits, wherein each comparator circuit generates an active comparator signal in response to a voltage difference between a first comparator input and a second comparator input. Each first comparator input is connected to one of the data signal lines. A ramp generator circuit includes at least one resistor network and buffer circuits. The ramp generator circuit generates a voltage ramp signal based on voltages at voltage tap nodes of the at least one resistor network. Each buffer circuit passes a buffered voltage ramp signal to the second comparator input of at least one of the comparator circuits.
