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 5):
The imaging system of  claim 1 , wherein:\n the first charge-to-voltage converter comprises:\n a first end coupled to an anode of the photodiode; and \n a second end for outputting the output voltage; and \n the biasing circuit comprises:\n a first transistor including:\n a first end coupled to a cathode of the photodiode; \n a second end; and \n a control end; \n \n a second transistor including:\n a first end; \n a second end coupled to the control end of the first transistor; and \n a control end coupled to the control end of the first transistor; \n \n a third transistor including:\n a first end; \n a second end coupled to the second end of the first transistor; and \n a control end coupled to the second end of the first transistor; \n \n a fourth transistor including:\n a first end coupled to the first end of the third transistor; \n a second end coupled to the control end of the first transistor; and \n a control end coupled to the second end of the first transistor; \n \n a fifth transistor including:\n a first end coupled to the first end of the third transistor; \n a second end coupled to the second end of the first charge-to- voltage converter; and \n a control end coupled to the second end of the first transistor; and \n \n a voltage source coupled between the anode of the photodiode and the first end of the second transistor to provide the constant bias voltage.
