A baseline restore circuit includes a current input for receiving a current pulse having a DC current baseline; a charge amplifier having an input coupled to the current input, and an output referenced to a DC voltage baseline; a feedback baseline restore circuit comprised of a switched capacitor integration circuit having an input coupled to the output of the charge amplifier, and an output coupled to the current input; and a sample control circuit controlling the switched capacitor circuit input to the integrator so that only the reference voltage baseline is sampled. The inputs to the sample control circuit are a window comparator, and a high rate pulse detector, both with inputs from the charge amplifier output.

Baseline restore sampling method

An integrated application specific integrated circuit having a detection layer, a time delayed integration capability, data acquisition electronics, and a readout function is provided for detecting breast cancer in women. The detection layer receives x-ray radiation and converts the received energy to electron pairs, one of which is received by pixels. The time delay integration is on the chip and a part of the readout architecture. The detector may be a hybrid silicon detector (SiPD), a CdZnTe detector, or a GaAs detector.
