COMPARATOR FOR ELECTRIC FIELD COMMUNICATION DEVICE, ELECTRIC FIELD COMMUNICATION DEVICE AND COMPARISON METHOD

摘要

PROBLEM TO BE SOLVED: To efficiently suppress spatial propagation, when an object approaches.;SOLUTION: A value of an input signal received by an electrode 3 is powered (V→V²) and is compared with a reference value Vth by using the value V² of the input signal after conversion. Thus, a set margin of the reference value Vth to be stored in a storage circuit 11 can be increased; and thereby, since the reference value can be adjusted finely; as a result, a signal transmitted by spatial propagation can be unfailingly removed as a noise; and the spatial propagation, when a possessing person A approaches another person B can be suppressed efficiently.;COPYRIGHT: (C)2012,JPO&INPIT
