Hsinchu, Taiwan 3 National Taiwan University, Taipei, Taiwan 4 University of New Castle, Callaghan, Australia 2 Simultaneous neural signal recording from many neurons has a wide range of applications ranging from the study of the complex biological neural networks to brain controlled neural prostheses to treat spinal cord injuries by restoring limb movement [1]. Wireless transmission of the recorded signals combined with on-chip neural spike sorting (a recording electrode senses the activity of an ensemble of neurons) is required for miniaturized and untethered neural recording systems. For neural prosthetic applications where the neural signals are translated to command signals for muscle stimulation, on-the-fly spike sorting and calibration is crucial for effective
