  • Abstract
    The problem of capacitor mismatch error in a switched-capacitor voltage divider (attenuator) is addressed. It is shown that, with the help of a ratio-independent voltage multiplier (amplifier) proposed earlier, it is possible to make the error in the voltage divider arbitrarily small, at the expense of time. This precision voltage divider is expected to be useful in a wide range of precision analog signal-processing applications.
