Abstract
An A/D converter circuit that converts analog information to numerical data is provided with a pulse delay circuit and an output unit. A sampling period is set so that a relationship between the sampling period and a circulation period of a pulse signal passing through a ring delay circuit satisfies a relational expression Trdl×n<Ts ≤Trdl×(n+1). In the relational expression, Ts is the sampling period, Trdl is the circulation period in which the pulse signal circulates through the pulse delay circuit, and 'n' is an integer equal to or greater than 0.
