چکیده
A nonlinear LCR parallel circuit model of a single photon avalanche diode (SPAD) is derived from Lienard-type differential equation. The resistance and the inductance associated with multiplication (AM) are time-dependent governed by time constant due to impact ionization ratio. Time dependences current, voltage, resistance, in analyzed numerically solving During initial generation Geiger-mode pulse, when voltage reaches breakdown diverges limit maximum current reduces give speed variation constant. In frequency domain, impedance (AI) spectra obtained as ratio calculated Fourier transforms domain signals. AI exhibit negative-resistance an inductance. An analytic expression for found comprise only quenching stray capacitance indicated radius Nyquist plot. Finally, present shown incorporate models impact-ionization-avalanche transit-time (IMPATT) diodes very small-signal assumed.

A 130nm CMOS Single Photon Avalanche Diode
We report on the first implementation of a single photon avalanche diode (SPAD) in 130nm CMOS technology. The SPAD is fabricated as p+/nwell junction with octagonal shape.

We propose the use of dynamic circuits for quenching avalanche events in single photon avalanche diode (SPAD) arrays. Two area-efficient, circuit solutions are presented in 0.35μm CMOS technology. These circuits contain no passive elements and consume shoot-through current only at triggering instants. The resulting reduction in power consumption and supply noise is essential to formation of lar...
