Abstract

A time constant calibration device includes: a first voltage generating circuit utilizing a first current passing through a capacitive component to generate a first voltage; a second voltage generating circuit utilizing a second current passing through a resistive component to generate a second voltage; and a comparing circuit for comparing the first voltage with the second voltage to generate a comparing signal, wherein the first voltage generating circuit comprises an analog adjusting component for adjusting the first voltage according to the comparing signal until the first voltage is equal to the second voltage, whereby an RC time constant defined by an equivalent capacitance corresponding to the first current passing through the capacitive component and an equivalent impedance corresponding to the second current passing through the resistive component reaches a predetermined value.
