AB  - Brain-machine Interface (BMI) with implantable bioelectronics systems can provide 
      an alternative way to cure neural diseases, while a power management system plays 
      an important role in providing a stable voltage supply for the implanted chip. a 
      prototype system of power management integrated circuit (PMIC) with heavy load 
      capability supplying artifacts tolerable neural recording integrated circuit 
      (ATNR-IC) is presented in this work. A reverse nested miller compensation (RNMC) 
      low dropout regulator (LDO) with a transient enhancer is proposed for the PMIC. 
      The power consumption is 0.55 mW and 22.5 mW at standby (SB) and full stimulation 
      (ST) load, respectively. For a full load transition, the overshoot and downshoot 
      of the LDO are 110 mV and 71 mV, respectively, which help improve the load 
      transient response during neural stimulation. With the load current peak-to-peak 
      range is about 560 muA supplied by a 4-channel stimulator, the whole PMIC can 
      output a stable 3.3 V supply voltage, which indicates that this PMIC can be 
      extended for more stimulating channels' scenarios. When the ATNR-IC is supplied 
      for presented PMIC through a voltage divider network, it can amplify the signal 
      consisting of 1 mV(pp) simulated neural signal and 20 mV(pp) simulated artifact 
      by 28 dB with no saturation.
