<p><P>PROBLEM TO BE SOLVED: To obtain a UWB (Ultra Wide Band) receiving circuit which can reduce power consumption while attaining simplification of a circuit. <P>SOLUTION: During a time with no transceiver signal, operation of an amplifier 2 is made to stop even in receiving time, a timing control of a switch 3 for stopping operation of the amplifier 2, is made by a timing control of a template signal Sterm inputted to a succeeding mixer circuit 5, a single pulse is used as the template signal Sterm for taking correlation with the receiving signal, and a template pulse creation circuit 4 is formed by a digital circuit. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
