Abstract:
An example imaging system includes a plurality of pixel circuits each having a photodiode, a biasing circuit and a charge-to-voltage converter. The photodiode is configured to generate charges in response to light or radiation. The biasing circuit includes an operational amplifier having an input signal port for receiving a bias reference signal which controls a bias current flowing through an internal circuit of the operational amplifier. The charge-to-voltage converter is configured to accumulate the charges drained by the biasing circuit and convert the accumulated charges into a corresponding output voltage.

Claim (Index 16):
An imaging system, comprising:\n means for operating an operational amplifier in a low power state with low bias current flowing through an internal circuit of the operational amplifier during an image acquisition period of a photodiode so as to drain charges generated by the photodiode in response to light or radiation and provide a constant bias voltage across the photodiode; means for operating the operational amplifier in a high power state with high bias current flowing through the internal circuit of the operational amplifier during a reset period or a readout period of the photodiode so as to output an output signal and provide the constant bias voltage across the photodiode; means for accumulating the charges drained from the photodiode in a first charge-to-voltage converter and converting the accumulated charges into the corresponding output voltage during the image acquisition period; and means for acquiring a signal sample by reading the output voltage during the readout period subsequent to the image acquisition period, wherein the signal sample voltage is associated with the charges accumulated in the first charge-to-voltage converter during the image acquisition period.
