Abstract

An offset integrator and method are provided to induce integrator leakage while simultaneously latching and canceling its own offset. The method includes combining a first and second input signals with a part of the output signal of a different polarity to produce a charge signal. An accumulation of the charge signal on a plurality of storage components is used to reduce the offset component of the output signal and simultaneously inducing an integrator leak. A positive and negative components of the input signals are combined with a negative and positive offset components of the part of the output signal, respectively. The method liner includes modifying a positive and negative components of an in-phase and a quadrature signal. A reset signal may be provided to erase a plurality of memory locations. A gating scheme may be used to provide a predetermined signal to produce a two-phase, non-overlapping signal. The two-phase non-overlapping signal also produces a predetermined delayed two-phase, non-overlapping signal. The gating scheme provides proper timing signals without the use of complementary clock phases.
