An image sensor includes an avalanche diode, an avalanche detector circuit, a sample and hold circuit, and a sample collection circuit. The avalanche diode has an output voltage that changes in response to an avalanche event in the avalanche diode. The avalanche detector circuit is configured to generate a sample capture signal in response to detecting the avalanche event. The sample and hold circuit is configured to store a sample of the output voltage in response to receiving the sample capture signal. The sample collection circuit is configured to collect the sample of the output voltage from the sample and hold circuit.
