  • Sigma-delta ADC with test circuitry
    Patent number: 8830098
    Abstract: The invention concerns a sigma-delta switched capacitor analog to digital converter (ADC) having: an input line for receiving a signal to be converted; first, second and third inputs for respectively receiving first, second and third test voltages; and switching circuitry adapted to apply, during a test mode of the sigma-delta ADC, a ternary test signal to the input line by periodically selecting, based on a digital test control signal, one of the first, second or third test voltages to be applied to the input line.
    Type: Grant

  • SIGMA-DELTA ADC WITH TEST CIRCUITRY
    Publication number: 20130201046
    Abstract: The invention concerns a sigma-delta switched capacitor analog to digital converter (ADC) comprising: an input line (405) for receiving a signal to be converted; first, second and third inputs (408, 410, 412) for respectively receiving first, second and third test voltages (VA, V0, VB); and switching circuitry adapted to apply, during a test mode of said sigma-delta ADC, a ternary test signal to said input line by periodically selecting, based on a digital test control signal (Dtest), one of said first, second or third test voltages to be applied to said input line.
