Embodiment Construction
[0022] The present invention will be further described below in conjunction with drawings and embodiments.
[0023] Such as figure 1 , in the analog front-end and A / D conversion circuit, the signal output by the nuclear detector is sent to the low-noise operational amplifier OPA843 for amplification after passing through the pole-zero phase cancellation circuit, and then sent to the A / D conversion chip AD9224 after shaping. AD9224 operates at a 40MHz clock The signal is continuously collected under control, and the collected data is directly sent to the CPLD for processing.
[0024] The A / D conversion circuit adopts AD9224 from Analog Devices, which is a 12-bit high-precision high-speed analog-to-digital converter, powered by +5V analog voltage, +3V or +5V digital voltage, providing reference voltage and high-performance sampling on-chip Hold amplifier; the sampling rate is 40MHz, and the input signal can be single-ended or differential. This design adopts single-ended input...
