This brief presents a boost converter with high efficiency for thermo-electrical energy generator (TEG). An on-time calibration based pulse skipping modulation (OTC-PSM) scheme is proposed to reduce the power of the controller. A hardware-efficient maximum power point tracking (MPPT) circuit is introduced for the constant internal resistance source of TEG. The proposed design has been implemented in a standard 180 nm CMOS process, achieving a high efficiency of 83.9% at 120mV input voltage and output power of 600 $\mu \text{W}$ . The proposed OTC-PSM scheme saves considerable power in achieving high efficiency as well as low output ripple. Also, the proposed MPPT is simple and easy to implement for low cost.
