Abstract
Charge transfer devices typically include a periodically reset floating element output stage coupled to an FET amplifier for sensing the transferred charges. For reducing both low-frequency l/f noise and high-frequency reset noise, the duty factor of the device clocking signals and the reset signal are picked so that at a selected multiple of the clock signal repetition rate, the information component is in phase quadrature with the reset noise component. The charge transfer device output signal is then synchronously detected with a reference signal which is in phase with the selected multiple of the information component.
