Title: Analog/digital converter
Inventor: SUGINO KOICHI
IPC: H03M1/20
Filed: 2001-03-30
Abstract: PROBLEM TO BE SOLVED: To provide an analog/digital converter that obtains an analog/digital conversion value with enhanced resolution without increasing the cost. SOLUTION: A CPU 2 includes an additional signal generating means that generates additional digital data according to an analog/digital conversion program. A digital/analog conversion means 5 converts the additional digital data into analog data as an additional signal V1 and a voltage conversion means 6 divides the additional signal V1 by the number of bits to be extended. An arithmetic means 7 applies addition/subtraction to an output V2 of the voltage conversion means 6 and an input signal Vin , and gives its output V0 to the voltage conversion means 6 which converts the output V0 into digital data. In this case, a value that is A/D-converted is stored as an initial value when the additional digital data takes an initial value. The arithmetic means 7 calculates the input signal Vin and the output of the means 6 while varying the value of the additional digital data. A value resulting from applying analog/ digital conversion to the result is compared with the initial value, and the additional digital data when the conversion value is changed into the initial value are added to the initial value as low-order bits and the result is used for an analog/digital conversion value of the input signal Vin .
