In this paper, a wireless power transfer receiver is provided using a rectifier rectifier and a three-loop linear LDO regulator. The use of common rectifiers, ie, diodes, does not appear due to the high threshold voltage, the voltage conversion rate, or the proper output power. Therefore, in this scheme, active diodes instead of ordinary diodes, so that the rectifier works in less VAC, is preferable given. In this paper, a fully integrated 1X/2X rectifier is first provided in the range of 30 mW with all capacitors built into the chip. On the other hand, using a key arrangement in the chip, a suitable arrangement can be made in both 1X and 2X modes, so that the output capacitance difference in both modes is C4 and C3, respectively. Due to the need to adjust the voltage in different quantities, the simplest way is to use a linear regulator. In this design, a linear regulator of a three-ring LDO with a PMOS transistor, with a gain loop and an impedance reduction buffer (internal polar displacement to high frequencies) is presented. The results obtained from the scheme are in the range of the input voltage of 4-1.25 having output power of 32 mW and the VCR1 in the conditions of RL=5 K , in the 2X/1X modes are 0.78-0.88 and 1.3-1.6 respectively an‎d under similar conditions, the PCE2 in both 2X/1X is 75-90% and 68-82%, respectively. Finally, the output results in RL=100 , with output variations of 10 mV in the range of 10A-10 mA load current and FOM, 6.11 ps. With regard to the results obtained from the power output and load variation and output voltage, this design is suitable for medical applications with a power range between 10-100 mW.
