Compensation circuit and radiation detection system

The invention discloses a compensation circuit and a radiation detection system. The compensation circuit is arranged between an output end of a first-stage amplifier and an input end of a second-stage amplifier in the radiation detection system and comprises two resistors and one capacitor, wherein the first resistor is in parallel connection with the capacitor, and the connection point of the first resistor and the capacitor is in serial connection with the second resistor. The compensation circuit is applied in the radiation detection system, can enlarge phase margin of a second-stage loop circuit, enhance system stability and improve reading rate under the premise of not influencing the reading of first-stage loop gain stability of a circuit, and has low cost and easy implementation.
