  • System for calibrating a time constant of an integrated circuit, and integrated circuit provided with such a system
    Patent number: 8610610
    Abstract: System and method for calibrating a time constant R0Ci of an integrated electronic current-feedback continuous-time delta sigma analog/digital converter (modulator) having a variable-impedance filter coupled to input of the modulator, an analog input signal Vin of fixed frequency applied to the variable-impedance filter, wherein the analog input signal Vin attenuation engendered by the variable-impedance filter is measured, and the value of a time constant R0Ci in the modulator and value of the impedance of the variable-impedance filter are modified until an attenuation corresponding to the desired attenuation for the integrated electronic circuit modulator is obtained.
