Abstract
A detector circuit can include an integrator having an amplifier, a first feedback capacitor connected between an input and output of the amplifier, one or more additional feedback capacitors connected by at least one switch between the input and output of the amplifier, and a shunt capacitor connected to the output of the amplifier. The shunt capacitor can be selected to have a capacitance value greater than that of a minimum but less than that of a maximum feedback capacitance. The detector circuit can further include a sampling circuit having a sampling capacitor connected to the output of the integrator amplifier through at least one switch, wherein the sampling capacitor is separate from the shunt capacitor. A computed tomography imaging apparatus can include the detector circuit.
