Charge Integrator Amplifiers

Analog Devices’ charge integrator amplifiers convert the charge acquired by X-ray or photodiode detectors to a voltage. The channels are composed of CMOS transistors, using typical high input impedance CMOS gates. The integrators generate charge dependent voltages using a range of selectable capacitance values that accommodate a broad range of input charge values. The integrators are followed by single-ended input to differential output voltage amplifiers where offset and low frequency noise voltages are subtracted from the input voltages.
