Abstract:
An analog silicon photomultiplier system includes at least one analog pixel comprising a plurality of analog photodiodes (APDs), and a capacitor, a signal generator, a phase detector, and a compensation network. The signal generator is configured to generate and propagate a sinusoidal signal concurrently along first and second transmission lines. A capacitor is loaded on the first transmission line when an APD corresponding to the capacitor detects a photon. The phase detector is coupled with the first and second transmission lines, determines a phase difference between the first transmission line and the second transmission line and calculates a number of APDs that have fired from the phase difference. The compensation network is coupled with the second transmission line and the phase detector, and comprises a plurality of compensation capacitors, wherein the compensation capacitors are loaded on the second transmission line in proportion to the number of APDs that have fired.
