TH7426A/27A

- if RE is activated or always at high level (Timing Diagram - Figure 2), each stored charge is transferred to the rea-

dout capacitance; this continuous readout mode is recommended for long integration time.

Qs conversion into voltage is supported by the readout stage capacitance, linked to a low output impedance ampli-

fier. This capacitance is reset at V

bias, before each pixel readout operation (high level φ ).

Due to the “Vidicon” read out mode, Qb level needs adjustment so as to provide enough carriers to sustain photocurrent

and dark current during the integration time. Pixel antiblooming is also resulting from “Vidicon mode” since photodiodes

cannot consume more electrons than Qb.

Antismearing (frame to frame antiblooming) efficiency depends on the photodiode reset conditions, reverse bias recovering

need a minimum Qb condition such as :

Qb>Clat .V

where : - Clat is the individual lateral input node capacitance, Clat ~1.5 pF (including photodiode, bonding pads...)

where : - V is the photodiode bias : V = V - 0.78V - 8.7
