Summary:The utility model discloses an intelligent electrical stimulation circuit device. The intelligent electrical stimulation circuit device comprises an EMG (electromyography) sensor and signal processor (1), a band pass filter (2), a micro controller (11), a main switch (4), a comparison amplifier (9), an auxiliary switch (7), a feedback circuit (8) and a stimulation current generator (5). The intelligent electrical stimulation circuit device is characterized in that the EMG sensor and signal processor (1) synchronously acquires and processes real-time EMG signals of a human body, the signals pass through the band pass filter (2) and then are outputted to the micro controller (11), the micro controller (11) outputs frequency modulation signals to control on-off of the main switch (4) and outputs amplitude modulation signals which are transmitted to the comparison amplifier (9) through the main switch (4), the comparison amplifier (9) compares the amplitude modulation signals with signals of the feedback circuit,
