Binning pixels

A multi-pixel binned circuit, comprising:

• a plurality of low leakage pixels, each of the low leakage pixels comprising:
• a photodiode, having an anode and a cathode, the anode to collect electrons,
• generated by light or by other form of ionising radiation;
• a bin transistor, having
• a first terminal coupled to the cathode of the photodiode;
• a second terminal, configured to be coupled to a first terminal of a voltage reset switch (VRST) transistor;
• a gate, configured to be coupled to a controller to receive a bin signal;
• and
• an output amplifier circuit, having an input and an output, wherein the input is coupled to the cathode of the photodiode and to the second terminal of the bin transistor,
• the multi-pixel binned circuit further comprising an RST transistor, having
• a first terminal coupled to the second terminal of each of one or more bin switches from the plurality of low leakage binned pixels;
• a second terminal coupled to a reset voltage source;
• and
• a gate configured to be coupled to a controller to receive a voltage reset signal.
