IPC: H04N5/357
Filed: 2001-06-20
Abstract: PURPOSE: To always minimize noise component even if production variation occurs in transistor characteristics, resistance value and the like. CONSTITUTION: K pieces of clock phase difference generation circuits 16-18 shift the phase of basic clock signal ADCK1 by different predetermined values and supply them to an A/D converter as a clock signal ADCK2. K pieces of counters 19 sequentially select each of the clock phase difference generation circuits 16-18 and stores the noise component of A/D converter output which is determined by noise measurement circuit 27 in corresponding resistors at each selection. A comparator circuit 25 compares k noise components to find the number j for the smallest value. Selection circuit 26 fixedly selects only jth clock phase difference generation circuit. Thus, even if a variation occurs in the transistor characteristics or the resistance value in individual device, the clock signal ADCK2 which shifted the phase of the basic clock signal ADCK1 can be supplied to the A/D converter to minimize the noise component.
