Abstract

PURPOSE:To obtain an A/D converter which is used for the data collector or the like with no effect of the noise component, by using the integrator capable of setting the initial state. CONSTITUTION:Analog signal Ai containing the noise component is supplied to the integrator with initial state setting consisting of resistance R, switch SW2, capacitor C and amplifier A3 each and via amplifier A2 and switch SW1. The intergrator delivers the input signal via switch SW1 after integration for a fixed time, and thus the analog voltage is delivered with the reduced effect of noise component. This output of the integrator is applied to A/D converter circuit AD via sample holding circuit SH and then delivered in the form of digital signal Do.
