Pulse current sampling circuit

The utility model discloses a pulse current sampling circuit, its characterized in that: including input voltage follower circuit, filter circuit, sampling holder and delay circuit, the input input pulse current's of input voltage follower circuit voltage sampling signal, the output of input voltage follower circuit passes through the signal input part that filter circuit connects sampling holder, and pulse current control signal inputs sampling holder's control end through delay circuit, the sampled signal of sampling holder's output output pulse electric current. The utility model discloses an advantage realizes simply, with low costs for this pulse current sampling circuit, can effectively avoid during my school of pulse current current sampling value's influence, effectively avoids pulse current to be in the influence of discontinuous mode, electric current variation period factor such as unset to current sample to strange high pulse current's sampling precision. 本实用新型公开种脉冲电流采样电路，其特征在于：包括输入电压跟随器电路、滤波电路、采样
