The invention discloses a compensation device and a compensation circuit thereof. The compensation circuit comprises an external power supply, a differential amplifier, a first diode, a triode, an MOS tube and a low dropout regulator. Wherein the differential amplifier judges whether the compensating circuit is in a high-power working state and whether the equipment chip needs to compensate the voltage by detecting the voltage difference between the two ends of the first diode. According to the compensation device, the problem that the equipment is shut down due to power failure of an equipment chip when the wireless communication equipment transmits signals is solved, logic judgment is carried out by adopting the hardware logic circuit, the stability of the compensation device can be effectively improved, the compensation circuit is simple in structure, and the practicability and economical efficiency of the compensation device are greatly improved. 本发明公开了一种补偿装置及其补偿电路，补偿电路包括：外接电源、差分放大器、第一二极管、三极管、MOS管和低压差线性稳压
