Apparatus and method for automatic correction of pole-zero error in a spectroscopy system |
摘要 |
A spectroscopy system is provided having an automatic pole-zero error correction circuit. A gated integrator of the system integrates a shaped pulse and trailing edge of the shaped pulse for sampling by an analog-to-digital converter. A pair of samples are converted along the slope of each integrated shaped pulse passing through the system. The two samples are compared on a pulse by pulse basis. An algorithm generates a control word for affecting a change in a pole-zero network coupled along a shaping amplifier of the system. In response to the control word, an MDAC of the pole-zero network affects a change in the system to correct the pole-zero error. When the pole-zero error is eliminated or reaches an acceptable user level, the correction circuitry automatically shuts off. |
