Title: CHIP POSITION-RESET APPARATUS
Abstract:
Provided is a chip position-reset apparatus, comprising a single chip microcomputer (1), a modulation unit (2), a resonance unit (3), a demodulation unit (4), a filter unit (5), and a shaping unit (6); the modulation unit (2) and shaping unit (6) are each connected to the single chip microcomputer (1); the modulation unit (2), resonance unit (3), demodulation unit (4), filter unit (5), and shaping unit (6) are sequentially connected in series; the shaping unit (6) comprises an amplification module (61) and a comparison module (62); the amplification module (61) is connected to the filter unit (5). By means of the filter unit (5), the chip position-reset apparatus filters a demodulation signal and adjusts the effective amplitude of the signal, then passes the filtered demodulation signal through the amplification module (61) and amplifies the demodulation signal such that the amplitude of the demodulation signal is increased; thus a weak demodulation signal can be amplified to a normal signal amplitude, and, upon performing a comparison of the amplified signal via the comparison module (62), the amplitude of a data signal is unified to an amplitude required by the single chip microcomputer (1); the single chip microcomputer (1) can thus receive and analyze all signals, thereby improving the sensitivity of recognition of chips by the chip position-reset apparatus and significantly increasing position-reset efficiency.
