Abstract
Circuitry for generating a histogram of output codes produced by an analog/digital converter (ADC) on an integrated circuit chip includes a comparator, disposed on the chip together with the ADC. A first input of the comparator is coupled to receive output codes from the ADC, while a second input is coupled to receive a sequence of target codes covering at least a portion of a range of the output codes. A pulse generator is disposed on the chip together with the ADC and the comparator, and coupled to receive the output of the comparator and, when the output is in the first state, to generate pulses for output from the chip at a pulse rate determined by a clock signal of the ADC.
