Analog spiking neuron circuit based on CMOS

The invention discloses a neuron circuit based on analog pulses, and belongs to the technical field of integrated circuits. The circuit comprises an integral accumulation module, a threshold issuing module and a voltage discharge module, the integral accumulation module, the threshold distribution module and the voltage discharge module are sequentially connected with one another, and the voltage discharge module discharges integral voltage by a fixed value after neurons distribute pulses each time. The neuron circuit provided by the invention can prevent input information from being lost, and ensures the integrity of the input information and the working precision of a neural network to the maximum extent; each module only uses a few MOS tubes and capacitance-resistance devices to realize basic functions of neurons, the external input control signals are less, the power consumption of the used devices is low, and implantable application or portable application is facilitated; the same reference source can pr
