An animal spinal cord neural signal regeneration circuit is presented in this paper. The circuit consists of an on-chip amplifier which was designed in TSMC 0.18μm 1P6M standard CMOS process and an output circuit using an off-chip high voltage transistor. A low temperature drift bias circuit and a constant-gm rail-to-rail input circuit employing a novel structure called Max Current Selection are designed in the amplifier. The amplifier occupies a die area of 300μm×300μm. The simulation results show that the consumption of the amplifier is about 1.45mW and gain of the whole circuit is 40dB. The output voltage reaches a wide swing of -1V∼4V under +5V and -1.5V off-chip power supplies. The circuit is expected to be used in vitro test for regenerating neural signals of animal’s damaged spinal cord nerve, as a new method for trying to cure nervous injury.
