Claim One:
1. A method, comprising: sampling an input signal with first and second banks of switched capacitor sample circuits during corresponding first and second sample phases; transferring sample charge from capacitors of the first and second bank sample circuits to an accumulator during corresponding first and second charge transfer phases; generating a digital feedback control signal to indicate of a number of the capacitors of the first and second banks to use to remove charge from the accumulator; and removing charge from the accumulator through the capacitors of the first and second bank sample circuits during the corresponding first and second charge transfer phases, including selecting capacitors of each of the first and second bank sample circuits, in accordance with the digital feedback control signal, to utilize each of the first bank capacitors a substantially equal number of times relative to one another over multiple sample cycles, and to utilize each of the second bank capacitors a substantially equal number of times relative to one another over the multiple sample cycles.
