In addition, the new design is based on regular cells and fully modular, which leads to good scalability and straightforward assembly into large systems.

In this work, a micromechanical TMR accelerometer based on electrostatic force feedback is proposed. A permanent magnet film is connected with the seismic mass. The input acceleration leads to a certain displacement of the sensitive structure, thereby causes the change of the magnetic field strength. The magnitude of the acceleration is obtained by detecting the evolution of the magnetic field. On the other hand, the feedback force that pulls the mass back to the initial position is continuously generated, therefore, the mass is always in an equilibrium position. According to the simulation analysis, the simulated sensitivity of the sensitive structure is 125.6um/g and the maximum value of the magnetic field intensity changing with the displacement is 0.1mT/mm. Consequently, the mechanical sensitivity of the micromechanical accelerometer in our proposal design is 12.56uT/g.

Under HCI effect, many electrical characteristics such as threshold voltage, trans conductance, drain-source current, gate leakage current, etc, will be obviously changed during a long period of operation time and under different voltage stress. The method of directly modifying SPICE model to simulate HCI effect is complex, and it may lead to non-convergence. Based on an NMOSFET model of a 65nm CMOS PDK, adding some common electrical components and arithmetic units to form an equivalent circuit is a practical way. This model has 4 input parameters, such as width of gate (W), length of gate (L), environment temperature (Temp), operation period (Year). The voltage stress of drain source, drain-gate, gate-source are also considered in this model. The simulation results show that the electrical performance of NMOS transistor under HCI is fitted many measured data of published papers.
