A novel charge pump with current mode control suitable to work under a very-low-voltage supply is proposed in this paper. The proposed charge pump consists of two sections. The first section is a power switches stage which consists of seven cascaded DEPMOS power switches. The second section is a low voltage stage which consists of a Low Voltage Level Shifter, Current Mode control, Follower Amplifier, Error Amplifier, Soft Start Comparator, and Skip mode & Over Voltage Comparator. The charge pump has been designed, simulated, and layout in Cadence using TSMC 130 nm SOI technology with LDMOS transistors, which have very low on-resistance. The input range of the charge pump is 2.7– 4.4 V, and it can supply up to 100 mA load current. The maximum efficiency is 90%, and the chip area is only 0.597 mm².

In this paper, a nonlinear controller is proposed to manage the rotational speed of a full-variable Squirrel Cage Induction Generator wind turbine. This control scheme improves upon tractional vector controllers by removing the need for a rotor flux observer. Additionally, the proposed controller manages the performance through turbulent wind conditions by accounting for unmeasurable wind torque dynamics. This model-based approach utilizes a current-based control in place of traditional voltage-mode control and is validated using a Lyapunov-based stability analysis. The proposed scheme is compared to a linear vector controller through simulation results. These results demonstrate that the proposed controller is far more robust to wind turbulence than traditional control schemes.
