Application specific integrated circuit (ASIC) of the electromagnetic-induction system |
摘要 |
The electromagnetic-induction system of the present invention comprises: a central processing unit (CPU); an application specific integrated circuit coupled with the central processing unit; a plurality of analogy switches that are coupled with the central processing unit and the application specific integrated circuit, individually; an antenna loop coupled with a plurality of analogy switches. The application specific integrated circuit further comprises: a digital filter that can reduce bandwidth error; a programmable gain amplifier that has the gain range with over eight-level; a latch device that can access the data at steady state; a multiplier and a divider that consist of hardware to increase the report rate; a programmable frequency generator can output the signal with the stable frequency.
