A Voltage Multiplier With Adaptive Threshold Voltage Compensation
IEEE Journal of Solid-State Circuits, 2017 A voltage multiplier (VM) with adaptive threshold voltage compensation is presented to enhance the power conversion efficiency (PCE). It is fabricated in a 0.18- $\mu \text{m}$ CMOS process. With the input frequency of 402 MHz and a load resistor of 30 $\text{k}\Omega $ , this VM achieves the PCE of 31.9% with the input power of −1 dBm, and ...
