High-voltage module circuit

The invention relates to the field of integrated circuits, and discloses a high-voltage module circuit, the circuit comprises a plurality of cascaded high-voltage modules, each high-voltage module comprises a first high-voltage module, a second high-voltage module, a first adjustable reference module, a first signal isolator and a second signal isolator, and when a first control signal is in a high level and a second control signal is in a low level, the first adjustable reference module is connected with the second adjustable reference module. The high-voltage module circuit outputs superposed positive voltage of the two high-voltage modules; and when the first control signal is at a low level and the second control signal is at a high level, the high-voltage module circuit outputs a superposed negative voltage of the two high-voltage modules. According to the high-voltage module circuit provided by the invention, the stability and precision of voltage output are improved through cascade connection of the pl
