PURPOSE:To ealize reduction in size of circuit and independent operation of each circuit block by providing independent power supply for each circuit block. CONSTITUTION:The circuit blocks 11, 12, 13 are formed as the block in accordance with functions and respective blocks are provided with power supplies 14, 15, 16. Therefore, the blocks 11-13 can be operated independently when the power supplies 14-16 are given respectively. Thereby, since the circuit blocks 11-13 are not influenced at all by change of power supplies of other circuit blocks, a decoupling capacitor or a filter is no longer necessary. Moreover, since the blocks 11-13 are independent, the power supply of each block can be grounded as desired in the positive side or negative side. |
